do you mean a static (stays the same) or dynamic (automatic from your isp)?

Most broadband providers use DHCP (Dynamic Host Configuration Protocol) to automatically assign IP addresses to their customers' computers. In theory at least, you would get a new IP address every time you restart your DSL modem or cable modem or reboot your computer. This isn't always the case, however. Most ISPs have far more IP addresses available than they have customers. Many times, you'll get the same IP address that you had the last session, largely because of the way that many OSs operate. I've had the same IP address on my cable modem based broadband service for over 4 years now.
When Windows is configured for DHCP and first starts up, it checks to see if it was assigned an IP address previously. If it was, it asks the DHCP server if it may use the same address that it had previously. If the IP address is available, the DHCP server will usually allow the old IP address to be reused. This is by design, as it significantly reduces the load on the DHCP server.
When a Windows box gets a DHCP assigned address, it stores it in the Windows Registry and will attempt to recycle it at the next boot. The IP address is tied to the specific network adapter and if it's available from the ISP, it will use that IP every time. The only way to "force" Windows to get a new IP address is to change out the network interface card.
My Linux-based firewall exhibits the same behavior. It stores the IP address in a file and asks permission to reuse it the next time it boots up. Changing out the NIC is the only way to force an IP change on my ISP's system.
If you have a static IP address, you'll have to ask your ISP to have it changed. Most ISPs probably won't want to do this as managing IP addresses is a pain in the back; they're going to want a good reason to do this.
All of that said, why do you want to change your IP address?

The question I would ask is why. I can't imagine what that's going to change for you. If you are asking, I have a feeling you have some purpose in mind, which this will not have any effect on.
Your ISP either has you setup on a Static or Dynamic IP.
If it is Static, then you have to contact your ISP to request a new IP address. That would probably take a few days and quite a hassle.
If you are setup as Dynamic, then you get what you get from your ISP. While it's dynamic, I've found that the IP remains the same for awhile.
If you have Windows 2000 or XP, you can go to: Start, Run, type "cmd" to go to the command prompt.
Type "ipconfig". This will tell you what your ip address is.
To renew, type: "ipconfig /release", then "ipconfig /renew".
This releases and renews your IP address, and you might get a new IP address.

Click on Start Button and move on to Settings --> Control Panel in control panel select Network connections all the ethernet cards are displayed and select the ethernet card to which you want to change the ip address. Right click and select the properties of the ethernet card and then in general tab select TCP/IP and then select properties here you can change the ip address.

If you have a static IP address then simply buy another one and shuffle beteen them. If you have a dynamic IP address simply disconnect from the internet and then reconnect. I hope I have answered your question.

i always thought ip addresses were the address of your internet connection and that u couldn't change it. it's how some people track other's location over the internet. maybe i'm wrong

Most Internet Service Providers don't provide static IPs unless you pay specifically for them. Try shutting down your cable modem or DSL modem for about a minute. Then fire it back up and check.

i think you can just go to the command prompt (start->accessories) then where it says c:\ blah blah, you can type "ipconfig/renew" and it should do that...
but im not sure if it just reestablishes ur connection or if it ottally gives u a new ip address..
