dear sir/madam ,
Delegation not found at parent.
No delegation could be found at the parent, making your zone unreachable from the Internet.
Not enough nameserver information was found to test the zone http://sarkariresult.yarbook.com, but an IP address lookup succeeded in spite of that
please some one help me what should i take action to solve this error
Hi @yatendra22, thanks for posting.
Generally your subdomains will not have individual zonefiles, so they will not be properly tested by tools such as that. The subdomains would be a part of your primary domain name, so you would want to review "yarbook.com" going forward.
