I am having problems resolving
igpp.ucla.edu
When I start a query at the root servers, I eventually get a referral
to the four name servers for ucla.edu. When I query each of those
name servers, I get
; (1 server found)
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1
;; QUERY SECTION:
;; igpp.ucla.edu, type = A, class = IN
;; AUTHORITY SECTION:
igpp.ucla.edu. 6H IN NS igpp.ucla.edu.
;; ADDITIONAL SECTION:
igpp.ucla.edu. 6H IN A 128.97.94.1
This looks like a proper referral to the one name server for the igpp
sub-domain. I also get the "A" record for that name server.
But when I dump the cache on the nameserver on which I was doing my
queries, I do not see this glue information cached. If the information
is not in the cache, then when I do a query for the "A" record, I find
that I need that "A" record to be able to query the authoritative
name server for that sub-domain. There seems to be a "chicken-and-egg"
problem. Why does BIND 9.5.0-P2 not cache the glue information that
it receives from the four authoritative name servers for ucla.edu?
Thanks.
