This is not really a NetBSD problem.
Basically it means that your machine failed to reverse-resolve 127.0.0.1;
this failure can also be seen on some cluster workstations.
It used to be the case (prior to around November of last year, I
think), that the root nameservers had a PTR record to localhost. from
1.0.0.127.in-addr.arpa., and a corresponding A record. This changed,
basically when it was noted that some hosts exhibited this behavior
(depending on which root server was queried), when Paul Vixie espoused
the viewpoint that none of the roots should be propagating this
(arguably bogus, bsd-specific) information.
What's the right solution? Probably to add the line:
1.0.0.127.IN-ADDR.ARPA. IN A LOCALHOST.MIT.EDU.
to your /etc/namedb/named.local or named.mit file (depending on
whether you think this is a local change, or a bugfix).
Perhaps Ted could comment on why this was left out when the forward
RR (A) is there...
