Hi can someone help me to understand what this NSLOOKUP command's output

[x]$ nslookup sample.abc.com
Address:<-- ???

Name:   sample.abc.com

In the address part one with arrow pointing question mark. What does the hash before 53 stands for?

Thanks in advance

The hash is a separator between the IP of the server that replied to your request, and the port it's service was running on.

You got your reply from the server and it's DNS service was running on port 53. The # separates the two values.
