I am running windows xp pro, a website I like has blocked my IP address and I have been using proxies to access it, but I get tired of finding new proxies every 2-3 days when mine dies...

I have tried release/renew from ipconfig and also repair and disable/enable from windows network connections, as well as changing to other ethernet drops... I think I have even reformatted my comp once since I have been banned and I am stuck with the same IP addy... I think maybe the DHCP server has recorded my MAC address and decided that this should be my quasi-static IP... if I change to my wireless card it gives me a different IP, but this is an unacceptable long term solution because I get poor wireless reception...

any clue how I can convince it to give me a new one?

thanks,
fobmagi

Are you on cable modem or dsl? I'm guessing cable modem, or else you're sitting on a router that holds your connection solid...

If you have a router, you will need to release the IP through the router, not your computer.

Now, with brighthouse cable, my IP only renews every 4 to 6 months. I am behind a router, and even if I do try to renew it on the router, it gives me my old IP back.

You will usually get a different IP if you switch out network cards because of the MAC address. I have my cable modem going into a hub, that splits off to two wireless routers, giving each their own IP. I believe your IP may switch if you do the MAC spoofing (or whatever it's called) through the router.

You can't really. the dhcp server will lease IPs on a time basis (1 day, 1 week, etc.), depending on how it's setup.

Are you using a router or anything like that to access the internet? If so, ipconfig will not do anything for you. You will have to renew it via the router. Either way, chances are that the dhcp server you are pulling your IP from may be doing caching, which it why you usually get the same IP address.

Also, you may want to unplug your cable / dsl modem for about 10 minutes while you change your mac address on the router... Something else to try.

not on a router I have access too.. not cable either... its at my university... theres like a 100 port network switch that I have a drop from which goes straight to fiber connection.. the DHCP servers are on the other side of the fiber...

I have had this same fuckin IP for like 1.5 years now... and its a laptop, so I can't easily change network adaptors... I've tried disconnecting for a day or two hoping somebody new will snag my old IP, but it just doesnt happen :/

Ok, the switches are caching your MAC address for easy routing. Chances are that if they are connecting back to a fiber backbone, they are layer 3 switches which help in routing, so by keeping your ip address attached to your MAC address, it's easier on the network.

Also, since you're inside the university, it's highly unlikely that you are getting a world routable IP address and you are probably pulling something like 10.10.x.x or 192.168.x.x, etc. If you are, that's not actually your IP address to the outside world. Your IP to the outside world would be whatever address is assigned to the border router at your university. You might try going to www.whatismyip.com and see what the website shows as your IP address. Then do a start --> run --> type "cmd" --> hit ok --> type "ipconfig". See if what the website shows and what ipconfig shows differ. If they do, the website you are trying to get to is blocking the University's IP address and really no matter what IP you get internally at the University, you still would not have access to that website because the router will translate your internal address to your external address all the time.

If you are pulling a world routable IP address, then there really isn't a lot you can do without accessing the DHCP servers to release your MAC address and let you pull another.

I highly doubt you will have a world routable IP address. Because, the university is easily able to shutdown your network port should you be in non-compliance with University policy (ie. peer-to-peer), and they can better protect you from computer breakins (hacking (pc term. here)).

It's possible - definitely not guaranted - you could expire your cached address if you use another Ethernet MAC on the your cable. Bring in another laptop or stick a PCMCIA Enet card in and use it for awhile. If the alternate adapter works you at least know the problem is limited to your address.

Again, no guarantee. It depends on the router/switch policies & implementation.

And as bendsley said, it could be a bigger problem. Even if you manage to flop your address they could be blocking your university, or the university could be blocking them, which would mean time to get happy with proxies.

Why is the address being blocked? At this point, you'll have to figure that one out and then contact the administrators to get it un-blocked.

http://www.whatismyip.com/ and ipconfig match 129.118.XX.XXX

theyre not blocking the whole university because I can access it from other computers on campus... just not mine... I can even access it from other computers on the same switch and other computers attached to the same F*n line as me...

I am being banned from the game because I insulted one of the admins.... there were 3 admins at one time... and over the years 2 of them quit... then the third went power happy and banned me because I attacked his gf in the game (which was not against the rules)... I threw a fit and all of the top players started a riot on my behalf... he got pissed off and turned the game off... I helped talk one of the other 2 admins out of retirement and he restarted the game, but since he doesnt have enough time to run it, he made me and 2 good friends moderators... I have asked him to fix the IP ban.. but everytime I ask he changes the subject... so there is really nobody else to ask.. the only solution is proxies or for me to get a new IP...

It sounds like you were banned for a reason, and if you try to get around the ban, you will get smacked down harder for it. Accept it. Your system may be given an IP based on its port on the switch, or by your mac address. Try booting with an OS that allows you to spoof your MAC, wait a half hour or so and then try to get an IP with DHCP see if it’s the same thing you always get. On the command prompt, run ‘ipconfig /all’ check when the dhcp lease expires.

you can spoof your address within windows. If you go to device manager, and right click on your NIC card. Go to the advanced tab, and click on network address. Assign a new one under value.

This will only work under windows, so don't plug in the network cable until after windows has completely booted up once the change is made.

It's a convention but not all drivers pay attention to Network Address. Others expect the value to follow manufacturer ranges or they bail back to the hardware assignment. Check ipconfig /all to see if it's really changing, then plug in the cable.

Not a bad idea though. If your driver supports it, trying a bunch of addresses would be your best bet for invalidating the switch's MAC cache. Then again, you might get a midnight visit from your friendly net admin police.

Contact your school sysadmin and promise to buy him or her a cup of coffee (or whatever) if he or she will retire your ip address so that you can get a new one.
