I use comcast as my internet provider and I have noticed my IP address only changes if there is a power outage or if I unplug the modem. Is there part of OS X or a program that allows me have that reset when I want? Or do I just have to unplug the modem.
Thanks

Just curious, why are you wanting to get new IPs?

If you are running Panther, you can open the network preferences and in the TCP/IP tab, click on the Renew DHCP Lease and you MAY receive a new IP. However, this depends on your provider, your connection type, and other factors you have not provided.
Unplugging the modem for more than a few seconds sends a signal back to your ISP and they may issue your IP to another user coming online, or simply renew your old one.
I have had the same IP on adelphia cable for many months until there is more than a brief power outage or I unplug the modem for several minutes.

OK, here is why I want to change IP addresses. I turned my computer on this morning, left it on the login screen and never made it back to login before I had to leave and do some shopping and other stuff. Came back to my computer with the login screen still there, but with an open window behind it. Now I have left my computer on many times before and not had a problem with this happening. The open window was the main Root users home window. I do not have a root user established on my home machine. So I tried to restart my computer, but I had to hold down the power button (I have a 17" G4 iMac) to shut down and then start it back up. The login screen came back on like normal. Why I want to switch IP addresses is to stop a hacker if this is what happened. Now, my connection is a Cable Modem and my provider is Comcast. I have been connected with them since June and have not had this problem before.
Thanks for any help.

If your machine had been compromised by a hacker, changing IP addresses will not solve your problem. Be sure that the OS X firewall is enabled, or better yet, install a router to provide a secondary layer of insulation from the Comcast network.

Definitely. If a hacker is good enough to get in to your machine and enable root and then mess with things, they are surely smart enough to check nearby IPs for you if they want to come back. That is, assuming they didn't plant a trojan of some kind to report your IP when you connect/power up/login.
Turn on the firewall, get a router, and if you're worried, try Little Snitch.
