dig on RHEL6 has a different behavior than in RHEL5, related to the @server syntax:

root@rhel6# dig @some.dnsserver.com any some.example.com
dig: couldn't get address for 'some.dnsserver.com': not found

It seems it doesn't try to revolve the parameter for the specified dns server. Any idea why is that? Is it to avoid making another dns request?

This is normal behavior: If dig can't find the address of the nameserver you specified (using the nameservers listed in /etc/resolv.conf) it will tell you it "couldn't get address for" your requested server.

Either you typo'd the DNS server name or your local DNS can't map the name to an IP -- Try specifying the nameserver by IP address instead?
