Guys, I am a Network Administrator for a Internet Service Provider and most ISP's will do Dynamic IP's, statics are too hard to do when you have many customers because you have to assign a IP to every new customer with dynamic the DHCP server hands them out automatically and us Admins don't have to worry about it. Normally, when a server hands you a IP it gives you a lease time, this lease time can range from 5 hours to 7 days or more, whatever the admin decides. Normal time is between 3 to 7 days. So for those times if you release your ip and renew it you will get the same ip address all the time. The server looks at your MAC address of the device that is plugged into your modem (such as your router) the info for the lease holds your MAC of your router or computer so if you really want to get a new ip you would have to spoof your devices MAC or leave your device off at the time of the lease epiration, this will be tricky because you may not know when it is. All in all the only thing you can do is change your MAC and that should do the job. If it dosen't then you are probably set static and that can be good and bad but thats a different forum.
