[Pdns-users] Fwd: RE: 4th level names and SOA records

[Grant Keller]

That all make sense, the only part of the puzzle I am missing at this
point is why I have the same problem with google dns:

dig SOA gimpelevich.san-francisco.ca.us @8.8.8.8

; <<>> DiG 9.7.3 <<>> SOA gimpelevich.san-francisco.ca.us @8.8.8.8

Hey Grant,

I am pretty sure that what you're seeing is intended if the following
conditions are met:

1. You are querying the authoritative nameserver for the root zone
(san-francisco.ca.us)
2. The subdomain is delegated to a separate set of nameservers
3. Your authoritative nameservers are not set to perform recursion for the
IP you are querying from

When querying outside of your server, the SOA appears correct, which is what
the general public would get when trying to DIG for the SOA.

Hope this helps,

When I try, I am not on the name server, but I am querying ns2.sonic.net.

dig SOA gimpelevich.san-francisco.ca.us @ns2.sonic.net
