DNS Configuration issues

domain-name-system

I recently started using entrydns.net as my domain's DNS Manager. I have hosting from another webhost and they provided me with 

NS: ns01.domain.com, ns02.domain.com
A : x.x.x.x

Now in my domain (mydomain.com), I set the following NS Records:

ns1.entrydns.net, ns2.entrydns.net, ns3.entrydns.net

Now, in entrydns.net I set up the following only :

NS : ns01.domain.com, ns02.domain.com
A : x.x.x.x

Then I checked with Pingdom DNS Checker and found some strange errors. Can you please suggest ways to correct the problem.

http://dnscheck.pingdom.com/?domain=srijit.com

  1. Superfluous name server listed at parent: ns1.entrydns.net
  2. Superfluous name server listed at parent: ns2.entrydns.net
  3. Superfluous name server listed at parent: ns3.entrydns.net
  4. Total parent/child glue mismatch.
  5. Name server ns01.000webhost.com (31.170.167.6) does not answer queries over TCP.
  6. 2 different serials found.
  7. different SOA records found.

By setting NS records within your zone on entrydns.net, you're performing a delegation from their servers. This confuses things a bit because the entrydns.net nameservers consider themselves authoritative for the domain. Remove the NS records pointing to the other nameservers.

You should be hosting these zones exclusively on entrydns.net and making your changes there. If you want them to get the data from a different source (i.e. ns01.000webhost.com.), this should be accomplished with zone transfers.

If this nameserver didn't consider itself authoritative, it should be serving up an AUTHORITY section with no ANSWER to perform a delegation. Yet if we look at the NS records it returns...

# dig +norecurse @ns1.entrydns.net. srijit.com NS | awk '{print "    " $0}'

...we're being sent to different nameservers entirely.
