Questions about IP address

If you are IP banned, can you just change your IP and go back? Also, if someone knows my IP or my mac address can I be DoS'd?

    The organization that banned you can define the type of ban. They can ban you by your specific IP, an area IP ban (IE a whole city if they want) or if you banned from a game server, your GUID. I'm sure there are more, but from what I know, these are some of the common ones.

    And yes, if someone knows you IP address, you can be attacked.

    Can they ban my mac address?

    If it's a game server, probably not. I'd be surprised if a server management software had the capabilities to do that. If it's a network site, maybe. They could configure the firewall to scan the packet for a specific MAC. If you're smart enough, you can mask your MAC address. But again, it's a lot easier to just ban by IP.

    What did you do wrong?

    Oh nothing, I just got banned from a few IRCs for being mean to the moderators.
  5. They can not see your mac address anyplace in the packet. This is fundamental to how traffic is passed. Mac addresses NEVER leave the segment they are on. On top of this because of NAT even what your machine thinks is the IP address is not passed. So all they can get is ip address assigned to your router. The mac address they will see is the mac address of THEIR router leading back to you. There are some link types that do not even use mac addresses.

    This basic basic networking stuff on how layer 2 works.

    Yes for IPv4. But it is possible for IPv6. I should have just said no and left it at that. But we are ways away from completely using IPv6.
