Question

From the list of text junk I’m using regular expression. The following will do that job to parse proxy pattern
(\d{1,3}\.){3}\d{1,3}:\d{2,5}. But This pattern parse the text like this:

692.248.222.879:43780
692.83.47.579:43780

Which is not possible IP address. I want to know, how to skip this kind of ranges using regular expressions?

Tools I prefer: Java or C#, notepad++. However any languages will do.

Answer 1

try this:

\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]?)\b:\d{2,5}

‘

692.248.222.879:43780 
692.83.47.579:43780
192.168.1.1:27052

works with the last one only
