I can't lookup the PTR for e.root-servers.net (192.203.230.10). This
server is located at NASA, as far as I can see, and is supposed to be
served by ns{1,2,3}.nasa.gov according to for instance x.arin.net:
230.203.192.in-addr.arpa. 86400 IN NS ns3.nasa.gov.
230.203.192.in-addr.arpa. 86400 IN NS ns1.nasa.gov.
230.203.192.in-addr.arpa. 86400 IN NS ns2.nasa.gov.
The nasa.gov name servers are at:
nasa.gov. 300 IN NS NS3.nasa.gov.
nasa.gov. 300 IN NS NS2.nasa.gov.
nasa.gov. 300 IN NS NS1.nasa.gov.
NS1.nasa.gov. 300 IN A 198.116.4.189
NS1.nasa.gov. 300 IN AAAA 2001:4d0:8300:401::189
NS3.nasa.gov. 300 IN A 198.116.4.181
NS3.nasa.gov. 300 IN AAAA 2001:4d0:6300:401::181
NS2.nasa.gov. 300 IN A 198.116.4.185
NS2.nasa.gov. 300 IN AAAA 2001:4d0:2300:401::185
Trying PTR queries for 10.230.203.192.in-addr.arpa against the IPv4
addresses for ns{1,2,3}.nasa.gov, I get REFUSED from all of them. I
can't even reach the servers at the IPv6 addresses (no reply at all).
Anybody else seeing the same?
