How to find Port number of IP address?

Question

We can find out IP address of a domain name or URL. But how to find out Port number on which a domain name is hosted?

Answer 1

Quite an old question, but might be helpful to somebody in need.

If you know the url, 1. open the chrome browser, 2. open developer tools in chrome , 3. Put the url in search bar and hit enter 4. look in network tab, you will see the ip and port both

Answer 2

Port numbers are defined by convention. HTTP servers generally listen on port 80, ssh servers listen on 22. But there are no requirements that they do.
