If you're getting DHCP from IPcop, it will be caching DNS info for you. So I'd start by checking that it isn't affected first.
Next, is the Gentoo box recieving a dhcp address? Is it also recieving DNS from the DHCP server? I'd start by hardcoding the address and DNS settings. If that doesn't work, then try using a different DNS server (24.71.223.145 is SHAW, and it'll work fine for you).
