Not trying to be pedantic, but a web server (any ip server) is going to only see the mac address of IT'S nearest hop, probably it's default gateway. Anybody (including all the web clients hitting the site) will show up in the arp cache with the same mac as the local default gateway... so blocking this way wouldn't work. More likely your source IP address was blocked, or it was a hidden cookie or something like that. > me (4-5 years ago) I was always working over the same wireless connection. > Also, Computer 'names' are transmitted.
