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. We're going to
cover how to change your IP address in Windows 2000, XP, 2003, and Vista using
command prompt.
If your IP is static, then you CAN’T change it without
contacting your
ISP. Although not impossible, it is very rare that an ISP
would assign you a static IP without some sort of increased level of service
like a business account. However, an ISP can set a lengthy lease time for your
IP address and make it look like you've assigned a static IP. If you have a
long lease time (explained in this article) on your IP then you may not be able
to
change your IP address without leaving your modem or router
unplugged for a long period of time (more than 8 hours), or 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.
