Well, adding the other name servers to my resolv.conf file didn't resolve the issue. It appears that I loose name resolution after a period of time (somewhere around 5 - 15 minutes). I'll do more digging over the next few days.

All other interfaces on my network are static. I've added the other IP addresses mentioned in the other responses to my message, so we'll see how that goes. Thanks for the responses.

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).
