Microsoft DNS server creates an NS record for server’s hostname. What is it needed for?


This record is created by Microsoft DNS server by default. It points to your server using server's host name. If your server’s hostname is not FQDN (Fully Qualified Domain Name) then it may cause problems with domain registration and management. To avoid these problems you need to properly configure the server’s hostname.

It has to meet the requirements for Fully Qualified Domain Name (FQDN):

1. Be correctly resolved in DNS.
2. Have a correct PTR DNS record.

It can be verified at site.

1. DNS lookup form > Input your server name > Check A record.

The DNS tool should return an IP address of your server.

2. Reverse DNS lookup form > Input that IP address where your server name is resolved to > Click on RevDNS button.

The DNS tool should return the full name of your server.

Please refer to the following article for more information .

Additional solution: The other solution for avioding this situation, you can switch DNS server to Bind, it this case hostname record will not be added to domain DNS zone.
