We host the DNS for our domain.
Two weeks ago, the developer requested that we setup a new zone 'dev.ourdomain.com' and place two host records in it my.dev.ourdomain.com and admin.dev.ourdomain.com.
We added the zone to our DNS and added A records for the host.
Now a week later, some DNS servers like google (126.96.36.199) and gtei (188.8.131.52) will resolve the hosts, but others like OpenDNS (184.108.40.206 ) and ATT Uverse (220.127.116.11) cannot resolve it.
