Before trying any other methods to change your IP address, try turning off (or unplugging the power of) your Cable/DSL modem for five minutes. In many cases this will change your IP address. However, if that does not change your IP address, repeat the process for 8 hours (overnight works well) instead of 5 minutes. Hopefully this will result in an IP change.
If the above does not result in your IP address changing, please look through the below for the situation that best matches yours and attempt to change your IP address that way. Unfortunately you are not able to get your IP address to change in all cases, as it is ultimate determined by your ISP'sDHCP configuration (when you've got a dynamically assigned IP address, that is.)
Windows - Computer connected directly to the modem
- Get to a command prompt. (START, run, cmd).
- Type "ipconfig /release" (without the quotes, on the command line by itself).
- Type "ipconfig /renew" (without the quotes, on the command line by itself).
Windows (second option) - Computer connected directly to the modem
- Get to a command prompt. (START, run, cmd).
- Type "ipconfig /release" (without the quotes).
- Shut down computer.
- Turn off computer.
- Turn off all ethernet hubs/switches.
- Turn off cable/DSL modem.
- Leave off overnight.
- Turn everything back on.
Network with Router
- Log into the router's admin console. (Often http://192.168.1.1/)
- Release the IP address. (Method varies by router manufacturer)
- Turn off router, ethernet hubs/switches, and the cable/DSL modem.
- Leave off overnight.
- Turn everything back on.
If you are using a cable/DSL modem and a router, you may wish to connect your computer directly to the cable/DSL modem. Please note that this could significantly impact your system security. This allows your ISP's DHCP to issue you a new (hopefully changed) IP address based of the (hardware) MAC address of your computer's ethernet card.
If all the above has not worked to change your IP address and you have a router, check and see if there is a "Clone MAC Address" option. Using it should change your IP address; however, you'll only be able to do it once (in most cases).
These will not work in all cases. If all else fails contact your internet service provider (ISP) and ask them if they are able to change your IP address or how long your connection needs to be off for your IP address to change.
If you trying to change your IP address because you are just trying to access web based forums you may wish to attempt to configure your internet browser to use a proxy server.

How do I change my IP address?
Question:
How do I change my IP address?
Additional information:
Users often want to change their IP address because of one or more of the below reasons.
- Network confliction or other network related issue.
- Network application requires specific IP address or IP range.
- Trying to protect themselves from other users.
- Trying to deceive a vicious software program, user, or company.
- See document CH000483 for additional information about determining your IP address.
Answer:
The basics
Before reading any of the below information, you need to be aware of some network basics.
- Know the difference between a static IP address and a dynamic IP address. See each of the links for additional information about each of these terms.
- When on the Internet, it is up to your Internet Service Provider (ISP) to assign and give you your network address seen by the Internet. Additional details posted below.
- If you're planning on designating and/or using a static IP address, you should be aware of how IP address ranges are handled and netmasks. See each of these links for additional information.
Changing your Internet IP address
Modem users
When connecting to the Internet, your ISP will assign your computer an address each time you connect. This means that often each time you connect you'll have a different IP address. If you're wanting to change your IP address, try disconnecting and reconnecting.
Broadband users
Almost all broadband service providers will assign your computer or home network a static IP address. If you're connected to a broadband network and need to change your IP address we suggest contacting your broadband provider.
Changing your home network IP address
Microsoft Windows users
To change or specify the IP address of your computer for your own local area network (LAN), follow the below steps. Keep in mind that if you're connecting to the Internet with a broadband connection, adjusting your network settings may cause issues with your broadband connection. Finally, if your home network is setup through a network router, that router could be assigning your computer dynamic IP addresses, and specifying a static IP address may cause issues.
- Get to the Microsoft Windows desktop.
- Right-click on My Network Places or Network Neighborhood and click Properties.
- Right-click on Local Area Connection and click Properties.
- Click Internet Protocol (TCP/IP) and click Properties. If this is not present, you'll need to install this protocol.
- In the Internet Protocol (TCP/IP) Properties window, select "Use the following IP address" if not already selected and specify the new IP address you wish to use. While entering this data you'll also need to specify the subnet mask and default gateway.
Linux users
The below information is for how to specify and adjust your network settings through the command prompt. Changing your network settings will require root access.
- Get to the command prompt.
- Move to the /etc/sysconfig/network directory.
- Edit the interfaces file and adjust your network settings in this file.
Additional information:
- See document CH000483 for additional information about determining an IP address.
- See document CH001047 for additional information about troubleshooting a IP address conflict.
How can I fix an IP conflict?
Question:
How can I fix an IP conflict?
Answer:
Often this occurs when the network or part of a network is not using DHCP to automatically assign IP addresses to computers, and something on the network has been manually assigned the same IP address as you.
If you're computer has DHCP enabled, often simply rebooting the computer allowing it to get a new address assigned to it will resolve the issue.
If you're not sure if you're using DHCP or are using a static IP address, either try to locate the computer or device using the IP address or manually change your IP address to something else. For example, if the address was 192.168.1.105 changing it to 192.168.1.112. Additional information about how to change your IP address can be found on document CH00784.

Solution:
Note: This document contains information about determining your own local IP address. If you're looking for information about obtaining an IP address of another computer or a website see document CH000962. If you're wanting to know what an Internet site sees your IP address as see our system information page.
Microsoft Windows Users
- Click Start / Run and type: "command" (without the quotes) to open a MS-DOS prompt.
- From the prompt, type "ipconfig" (without the quotes) and press enter. This should give you information similar to what is shown below.
Windows 2000 IP Configuration
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.101
Subnet Mask . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . : 192.168.1.1
As seen in the above example, the IP address as well as other important network information is listed when using the "ipconfig" command. If you have more than one network adapter, e.g. a wireless adapter and network adapter you'll see each adapter listed when using this command.
Home network and corporate network users
This information is the IP address of your computer in your network. If you're computer is connected to the Internet the IP address shown in this screen will more than likely not be the IP address other people and web pages see. To determine this IP address easily see the below online service section.
Graphical representation of network settings
Microsoft Windows XP users may get a GUI representation of their network by right-clicking the network icon in their systray and selecting "Status." Within the "Local Area Connection Status" window click the "Support" tab.
Microsoft Windows 98 users may also get a GUI representation of their network settings by clicking Start / Run and typing "ipconfig" in the run line. Unfortunately, not all versions of Windows have this feature.
Linux / Unix, BSD 4.2+, and Apple OS X, Operating System Users
For Linux or Unix users, to view their IP address or network information, users must have administrator or root privileges.
- Open the Linux or Unix shell if you are utilizing a GUI interface for your Linux or Unix machine.
- From the prompt, type "ifconfig eth0" (without the quotes) and press enter. This should give you a listing of network information similar to what is seen below.
eth0 Link encap:Ethernet HWaddr 00:A0:24:72:EB:0A inet addr:10.10.10.2 Bcast:10.0.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5569799 errors:32 dropped:32 overruns:0 frame:6 TX packets:3548292 errors:0 dropped:0 overruns:0 carrier:3 Collisions:14 Interrupt:18 Base address:0xda00
As seen from the above example, users will commonly see the network settings for all their network devices when running the "ifconfig" command. First in the above example we have the network settings for the "lo" or "local loopback", next is the actual network settings of your network adapter.
Home network and corporate network users
This information is the IP address of your computer in your network. If you're computer is connected to the Internet the IP address shown in this screen will more than likely not be the IP address other people and web pages see. To determine this IP address easily see the below online service section.
Apple Macintosh Users
- From the Apple menu, select the "Apple System Profiler"
- Open the "Network overview"
- Open "TCP/IP"
Within this window the user will be able to see the computer's network information including the IP address.
Home network and corporate network users
This information is the IP address of your computer in your network. If you're computer is connected to the Internet the IP address shown in this screen will more than likely not be the IP address other people and web pages see.

Internet Protocol Address:
This number is an exclusive number all information technology devices (printers, routers, modems, et al) use which identifies and allows them the ability to communicate with each other on a computer network. There is a standard of communication which is called an Internet Protocol standard (IP). In laymans terms it is the same as your home address. In order for you to receive snail mail at home the sending party must have your correct mailing address (IP address) in your town (network) or you do not receive bills, pizza coupons or your tax refund. The same is true for all equipment on the internet. Without this specific address, information cannot be received. IP addresses may either be assigned permanently for an Email server/Business server or a permanent home resident or temporarily, from a pool of available addresses (first come first serve) from your Internet ServiceProvider. A permanent number may not be available in all areas and may cost extra so be sure to ask your ISP.
Domain Name System (DNS): This allows the IP address to be translated to words. It is much easier for us to remember a word than a series of numbers. The same is true for email addresses.
For example, it is much easier for you to remember a web address name such as whatismyip.com than it is to remember 192.168.1.1 or in the case of email it is much easier to remember email@somedomain.com than email@192.168.1.1
Dynamic IP: One that is not static and could change at any time. This type of IP is issued to you from a pool of IP addresses allocated by your ISP or DHCP Server. This is for a large number of customers that do not require the same IP all the time for a variety of reasons. Your computer will automatically get this number as it logs on to the network and saves you the trouble of having to know details regarding the specific network configurations. This number can be assigned to anyone using a dial-up connection, Wireless and High Speed Internet connections. If you need to run your own email server or web server, it would be best to have a static IP.
Static IP: One that is fixed and never changes. This is in contrast to a dynamic IP which may change at any time. Most ISP's a single static IP or a block of static IP's for a few extra bucks a month.
IP version 4: Currently used by most network devices. However, with more and more computers accessing the internet, IPv4 IPs are running out quickly. Just like in a city, addresses have to be created for new neighborhoods but, if your neighborhood gets too large, you will have to come up with an entire new pool of addresses. IPv4 is limited to 4,294,967,296 IPs.
IP version 5: This is an experimental protocol for UNIX based systems. In keeping with standard UNIX (a computer Operating System) release conventions, all odd-numbered versions are considered experimental. It was never intended to be used by the general public.
IP version 6: The replacement for the aging IPv4. The estimated number of unique IPs for IPv6 is 340,282,366,920,938,463,463,374,607,431,768,211,456 or 2^128.
The old and current standard of IPs was this: 192.168.100.100 the new way can be written different ways but means the same and are all valid:
* 1080:0000:0000:0000:0000:0034:0000:417A
* 1080:0:0:0:0:34:0:417A
* 1080::34:0:417A

There are MANY methods to change your IP address. Some methods will work for you but may not work for someone else and vice versa.
If your IP is static, then you CAN’T change your IP address without contacting your ISP.
If you have a long lease time (explained in this article) on your IP then you won’t be able to change your IP without cloning your MAC address, which I’ll explain later in this article.
It definitely helps if you know how the IP is being assigned to you.
You can read our DHCP definition to get a better understanding.
What is an IP lease time? IP lease time is the amount of time your ISP determines you’ll be assigned a particular IP address. Some IP lease times are just a few days and other IP lease times could be set for a year or more. This setting is completely up to your ISP.
One of the easier methods to change your IP is to turn off your modem/router/computer overnight. Then turn it back on the following morning. This method WILL NOT work if your ISP has a long lease time set for your IP.
The following method will ONLY work if your computer is being assigned your external IP and not a router.
How to determine if your computer is being assigned the external IP
If your connection is direct to your computer and your computer gets the public IP and not a router, you can try this:
For Windows 2000, XP, and 2003
1. Click Start
2. Click Run
3. Type in cmd and hit ok
4. Type ipconfig /release and hit enter
5. Click Start, Control Panel, and open Network Connections
6. Find and Right click on the active Local Area Connection and choose Properties
7. Double-click on the Internet Protocol (TCP/IP)
8. Click on Use the following IP address
9. Enter a false IP like 123.123.123.123
10. Press Tab and the Subnet Mask section will populate with default numbers
11. Hit OK twice
12. Right click the active Local Area Connection again and choose Properties
13. Double-click on the Internet Protocol (TCP/IP)
14. Choose Obtain an IP address automatically
15. Hit OK twice
16. Go to http://www.whatismyip.com to see if you have a new IP address
For Vista
1. Click Start
2. Click All Programs expand the Accessories menu
3. In the Accessories menu, Right Click Command Prompt and choose Run as administrator
4. Type ipconfig /release and hit enter
5. Click Start, Control Panel, and open Network and Sharing Center. Depending on your view, you may have to click Network and Internet before you see the Network and Sharing Center icon
6. From the Tasks menu on the left, choose Manage Network Connections
7. Find and Right click on the active Local Area Connection and choose Properties (If you’re hit with a UAC prompt, choose Continue)
8. Double-click on Internet Protocol Version 4 (TCP/IPv4)
9. Click on Use the following IP address
10. Enter a false IP like 123.123.123.123
11. Press Tab and the Subnet Mask section will populate with default numbers
12. Hit OK twice
13. Right click the active Local Area Connection again and choose Properties
14. Double-click on Internet Protocol Version 4 (TCP/IPv4)
15. Choose Obtain an IP address automatically
16. Hit OK twice
17. Go to http://www.whatismyip.com to see if you have a new IP address
Some people have inquired about manually assigning their IP address. This IS possible, but you run a very high risk of your ISP banning you from connecting to the internet. To manually change your IP, follow the steps above for your Operating System. In step 9 or 10, depending on your O/S, enter an IP similar to the one displayed in the command prompt window. For example, if the IP displayed in the command prompt window is 75.1.2.3, change yours to 75.1.2.4. You’ll also need to manually enter the Subnet, Gateway and DNS Server IP addresses as well. If the new IP you give your computer doesn’t work, chances are someone else on the ISP network has already been assigned that IP. You’ll need to move on to the next one and keep trying until you find an open one. However, some ISPs match up your MAC or modem data to the IP that’s been assigned. If those 2 things don’t match up, you won’t be able to connect no matter what. If your router gets the IP and not your computer, you’ll need to http in to your routers interface and manually assign the IP there. It’s pretty much the same method as assigning the IP to your computer. The method that varies is in how you reach your routers interface. You can get the instructions from your manufacturer’s website. Our Router Support page can help point you in the right direction.
MAC Cloning. What is a MAC address? A MAC address is a physical hardware address assigned to each device that has the capability of connecting to a network. The internet is nothing more than a large network. The MAC address is something that is assigned in the chip on the device and is not something the user can change. MAC cloning can only be done at your router providing it has those capabilities. Most ISPs assign their IPs based on the MAC address in your equipment. If the MAC address of your router is 00-11-22-33-44-55 and you connect to your ISP, the DHCP server records your MAC and assigns an IP. If you disconnect from the ISP, you lose your IP address. The next time you connect, the DHCP server sees your MAC, looks to see if it has assigned an IP address to you before. If it has and the lease time has not expired, it will most likely give you the same IP address you had before disconnecting. Why clone a MAC address? New MAC address most likely equals new IP. How to clone your MAC and if your router has this feature is dependent on the router itself. You’ll need to find the instructions on the manufacturer’s website. Our Router Support page can help point you in the right direction.

Reasons to Change an IP Address
Even if you're part of a small network routed through a single IP address, the people outside your network can see only the IP address of the gateway you're using. If you're connected directly to the Internet cloud, it's basically the same thing. You're reaching out to a certain service through a certain IP address.
If someone would want to deny your access to certain services (an IRC channel, a certain forum, some websites, game servers and so on), they'd have to ban your IP address from the system. This puts you in a dilemma. The first thing that comes in mind is to change your IP address so you can evade the ban. Ban evasion is not recommended in any way as it may lead to a longer ban/denial of access. This doesn't have to be all negative. You can wish to change your IP address due constant flooding or spam you're being the victim of.
However, this tutorial will teach you a few tips and tricks on how to get things started in changing your IP address and how to actually change your IP address once the request has been approved.
If you're one of the old Dial-UP users with phone lines connected to your computer, you're most likely going to receive a different IP address if you're going to disconnect and reconnect the service. The same thing applies to those of you using PPPoE (Point to Point Over Ethernet) based on username/password since those are not permanent connections and they have to be reestablished every time you turn on your equipment.
The real problem comes for those of you using cable modems/DSL/FTTH connections. Most of you have static IP addresses, and if you don't, you probably have a bound IP address based on your Ethernet MAC address, so it still won't change.
The best thing to do in this case is to call your ISP and ask for suggestions on what to do next. Most likely, they have a special procedure regarding IP change requests. They will either provide detailed instructions on how to change your IP address either will give you the new settings available for immediate use.
In case of flooding and harassment, you might be asked for proof to sustain your statement. Get ready to show relevant logs extracted from your firewall and anything else you feel like it's going to be useful.
Once they have approved your request, you will only have to modify your settings, if your IP address is manually configured on the equipment. If so, you will have to change it to the new one your ISP gave you.
Steps to Change Your IP Address
| Operating System | Steps to Change the IP Address |
|---|---|
| Windows 9x/Me users | Go to Start -> Control Panel -> Network -> Network card -> TCP/IP -> IP address |
| Windows XP/2k users | Go to Start -> Control Panel -> Network Connections -> Local Area Connection -> Properties -> Internet Protocol (TCP/IP). |
| Red Hat Linux | Go to System Tools -> Network. You could also use tools as 'linuxconf' or 'netcfg'tool. |
Keep in mind that different ISP's have different procedures related to IP address changes and if you requested an IP change once and it was approved, it might not be approved so easily the next time.
