I have a subdomain dramarsarin.crimsonandcyan.com which i wanted to point to another server. I added an A record in the zone file for crimsonandcyan.com with the host 'dramarsarin' and pointed it to the server's ip address.

Now when i do a dns check on pingdom.com for my subdomain, i get this:

No delegation could be found at the parent, making your zone unreachable from the Internet.

How can i fix this? I do see that sometimes it takes too long to resolve the subdomain. That is why i think the analysis of pingdom.com is pretty valid.

  • Did you update NS record for this domain at any point? dig NS crimsonandcyan.com returns an empty response sometimes, this is likely the reason why you are getting this error from pingdom.com as well. – grekasius Jun 29 '14 at 8:37
  • Yes i did, but not recently. But i've checked that now they are set correctly. – Kanishk Dudeja Jun 29 '14 at 9:41
  • Disregarding the Pingdom error which looks to be a red herring, can you include dig output which demonstrates the problem? – Håkan Lindqvist Jun 29 '14 at 11:45
  • I tried the dig command, but i think everything works fine. Can i ignore the pingdom error? – Kanishk Dudeja Jun 30 '14 at 6:27

The Pingdom DNS check tool does not clearly state this but from its behavior it's clear that it expects the name of a zone, not just any domain name.

Ie, whatever you enter it expects that it should be a zone of its own (with delegation in place), which will not be the case in your example.

    Right. So do i actually need to make a zonefile separately for the subdomain? – Kanishk Dudeja Jun 30 '14 at 6:25

    @KanishkDudeja No. It's just that the pingdom check is not suitable for this purpose. – Håkan Lindqvist Jun 30 '14 at 11:33
