How to find Port number of IP address?
Unfortunately the standard DNS A-record (domain name to IP address) used by web-browsers to locate web-servers does not include a port number. Web-browsers use the URL protocol prefix (http://) to determine the port number (http = 80, https = 443, ftp = 21, etc.) unless the port number is specifically typed in the URL (for example "http://www.simpledns.com:5000" = port 5000).
Can I specify a TCP/IP port number for my web-server in DNS? (Other than the standard port 80)
Quite an old question, but might be helpful to somebody in need.
If you know the url,
- open the chrome browser,
- open developer tools in chrome ,
- Put the url in search bar and hit enter
- look in network tab, you will see the ip and port both
