The scenario is we will be adding new Host record on our internal DNS server and updates of those PTR records. How can i check if the dns A record has been completed propagated?

Answer 1

Hi,

You can use Nslookup command to check DNS Records. All your machines that point to your internal DNS will resolve A record and PTR record succesfully.

Nslookup A record or FQDN should return corresponding IP address. Nslookup IP address should return corresponding FQDN.

For more details about the command of Nslookup, you can refer to the following article:

nslookup
