They can be using the Mac address of your ethernet/wireless Card.
If you have a cable modem and live in a Time warner area unplugging it for a few hours and then rebooting might change your Ip but with many other isp you might have a more permanent Ip wich is changed at the ISP discretion unless your paying for a Static.

Dude if you sign in they are just going to ban your new address. Just let it go, send a nice e-mail to the admin and suck up. If you go around being sneaky about it you are just going to piss them off more and they are going to label you a problem and they will be looking for you wherever you go.

Rc is good at keeping people out. They log everything Mac adresses, Ip Email, Etc then they make up a list and ban everything on the list. If any piece of equipment or Ip on that lists shows up you'll get banned again. Good Luck

Unplug the modem they gave you for 72+ hours, that is your only chance of getting a new IP.
David, the MAC address is not used for security outside of the L2 domain. An internet host/site cannot filter based on MAC address. The MAC address of all packets destined for a host shows up as the MAC of the nearest upstream L3 device, so filtering by MAC is not useful for anything but the ISP who manages the connection.
I know you have way more knowledge than me at the It level

No, MAC addresses have L2 significance only. They are not included within the IP portion of a packet (unless it is an application that is purposely telling the server what its MAC address is, which is not something you do with internet traffic).
So when your machine sends out an ethernet frame, as soon as you get to the L3 boundary, the router takes the frame, strips off the MAC, puts its own MAC on, and forwards it out the destination port. The MAC is only relevant at the switch level as with every L3 hop the packet gets a new source MAC address.
The reason it is relevant in an ISP discussion is that the cable companies used to enforce the rule of 1 modem = 1 PC. Since the MAC addresses are assigned by the IEEE, the cable companies could look at the MAC OUI records, create a list of every MAC that was associated with Linksys, Netgear, Cisco, etc, and basically ban every address from that range. The manufacturers got wind of this and put in the MAC address cloning feature on the home routers that people buy, which allows you to take the MAC from your PC (which would be allowed by the cable company) and assign it to the internet port of the router, making the router look like the PC to the cable company.
But again, once it goes past a router, the MAC address of the host is lost, no significance and trying to filter on the remote side based on MAC addresses won't work.

To my knowledge the cable modem was not designed to talk to more than one MAC, the reason for the reboot was so the modem could strap to the MAC of the connected device when changed.
Dave....Plenty of reason to filter based on MACs, think your local bank; do you want the cleaning crew to be able to plug a notebook into the network? May sound funny but how often do you look under the desk for another device?
Jerl77... you can play musical IPs but they will catch up and ban the new IP, a cycle that gets pretty boring....plus do you really want to be 'that' guy, wait the month out and politely ask to be allowed back.

they r using ip filtering. change your ip will do it.
your cable modem can only work with a specific mac address is because the cable company wants u to pay if u wanna add another connection. however, routers with mac address cloning defeated that purpose. josh is right on the $

Maybe you shouldn't have been engaging in the behavior that got you banned in the first place? :scratchch:
How nice was your email to the admin? Did you apologize for your behavior? The more you try and be sneaky, the less likely they will ever consider un-banning you.
