I just entered the google numbers in dns in my router config and left the computer set for automatic. Worked fine.

Cox won't work at all for poserplace, neither will any of my 3 web servers, which are in 3 separate datacenters- 2 in Houston and 1 in Dallas.

Don't think it's IPV6, the ns records seem to indicate IPV4
It doesn't make sense that the google nameservers would work and the others won't (but google does work), unless google is more forgiving.
I'm thinking the phantom3d dns is screwed up somehow, I did notice some anomolies while digging for the nameserver records but didn't analyze them or anything.
