Welcome.

Looks like we are now not delegating. Sorry.
Will follow it up in the morning with a team member.

Some resolvers, ours included wont answer trace requests, its seen as cache snooping.
I would have to do a tcpdump an look but I suspect when dig does a +trace it is doing some queries without the RD flag set.

Could be what you are seeing with your trace attempts, could also be i haven't consumed nearly enough beer tonight and talking rubbish:)

Hi Paul,
Thanks for the assistance and pointing out a glaringly obvious problem :S.

NS records are all fixed but not seeing the delegation still. Should this happen now automatically or do Orcon still need to do something? I've now learnt how to use the Dig command but can't figure out how to trace it like in other posts.

Thanks,
Jonathan

Message-ID: <7d59cc8$6fc11687$642d0766$@xtracta.com>
Content-Type: text/plain; charset="us-ascii"

Hi everyone, Google have just started enforcing PTR records for IPv6
addresses delivering to Gmail. Our IPv6 works great with Orcon but having
serious issues getting delegation back to our nameservers setup. I have
been told a few times that everything is setup on their end but I don't
think it is.
Our IP space: 2400:4800:4017::/48 is meant to be sent to
ns1.power-business.co.nz and ns2.power-business.co.nz. However it doesn't
seem to. For example our website is:2400:4800:4017:200:250:56ff:fe90:82f
If I query ns1.power-business.co.nz from my home computer is works fine:
-----command-----
C:\Users\Jonathan Spence>nslookup 2400:4800:4017:0200:0250:56ff:fe90:082f
60.234.77.213 Server: UnKnown Address: 60.234.77.213
Name: midas.power-business.co.nz Address:
2400:4800:4017:200:250:56ff:fe90:82f
------ end command -----
However other hosts don't resolve this. When using this tool it doesn't
work failing when reaching Orcon's nameserver:
http://www.simpledns.com/lookup-dg.aspx
Can anyone comment?
Thanks, Jonathan

The reverse domain for 2400:4800:4017::/48 is 7.1.0.4.0.0.8.4.0.0.4.2.ip6.arpa. Your supposition is correct and ns1.orcon.net.nz does not seem to have delegated the domain to your nameservers.

I will take a look when I get to the office.
Sadly IPv6 records are manual at the moment, and its entirely possible its a typo.

OK we have had a good look into this and you have an issue you need to resolve.

The CNAME is illegal, this means we dont follow it.
RFC2181 section 10.3: Copied below:


10.3. MX and NS records

The domain name used as the value of a NS resource record, or part of
the value of a MX resource record must not be an alias. Not only is
the specification clear on this point, but using an alias in either
of these positions neither works as well as might be hoped, nor well
fulfills the ambition that may have led to this approach. This
domain name must have as its value one or more address records.
Currently those will be A records, however in the future other record
types giving addressing information may be acceptable. It can also
have other RRs, but never a CNAME RR.

Searching for either NS or MX records causes "additional section
processing" in which address records associated with the value of the
record sought are appended to the answer. This helps avoid needless
extra queries that are easily anticipated when the first was made.

Additional section processing does not include CNAME records, let
alone the address records that may be associated with the canonical
name derived from the alias. Thus, if an alias is used as the value
of an NS or MX record, no address will be returned with the NS or MX
value. This can cause extra queries, and extra network burden, on
every query. It is trivial for the DNS administrator to avoid this
by resolving the alias and placing the canonical name directly in the
affected record just once when it is updated or installed. In some
particular hard cases the lack of the additional section address
records in the results of a NS lookup can cause the request to fail.

Let me know if you need further assistance.
