How do I change my IP address?" and "Can I change my IP address?" are probably one of the most commonly asked questions.
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.
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.
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 you are trying to visit a site, which you happen to be banned from, you can simply use a proxy like https:vtunnel.com. A lot of people want to use Rapidshare, and have a free account and would like to download more than once in a certain period of time, well in that case you can download it off the offical site for free Once, and then you can use a program called Rapiddowner.
If this doesn't work you can manually configure your IP, by going to start>control panels> network connections> LAN network> properties> TCP/IP connection> properties. You can enter in your IP, but only change the end part of the address from something such as 192.168.1.100 or 192.168.1.101. The subnet should be the same.
If you use dial-up reconnnectioning the phone line and reconnecting to the internet shoudl automatically change your IP.
If ALL else fails, then call your service provider and ask them nicely for a new IP.
