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.
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.dig
output which demonstrates the problem?
