Hi,<br>
<br>
There is a problem with resolving names from dipmap.com with
unbound.<br>
Currently, the root NSs give back three nameservers, from which only
one works (at least from our network).<br>
And that one has a bad NS RR:<br>
$ dig ns dipmap.com @ns.dipmap.com.<br>
<br>
; <<>> DiG 9.6.-ESV-R4-P1 <<>> ns dipmap.com
@ns.dipmap.com.<br>

dipmap.com. 60 IN NS sql2005.<br>
<br>
It seems that unbound stores that nameserver and wants to query it,
so either a time out or a SERVFAIL happens to the client.<br>
<br>
I thought that a recursive DNS server shouldn't cache NS records
from the zone's authoritative name server, it should only trust in
the upper servers.<br>
ISC BIND doesn't have this behaviour -it seems-, so it can resolve
names from this domain.<br>
