Question

How can I extract all IP:PORT from a given website ? I have this current Regex PATTERN but i think it doesn’t grab all..

Or is it a better way to do it?

PATTERN = '((?:1?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:1?\d{1,2}|2[0-4]\d|25[0-5]):\d{2,5}';

Answer 1

This will work, if there is always a port following the IP:

\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\:\d{2,5}\b

Matches:

1.2.3.4:80
001.002.003.004:2345
255.255.255.255:13245

Does not match:

1.2.3
1.2.3:01
1.2.3.4.5:99
299.299.299.299:123
