Regular expressions matching IPv4 addresses: \b(?:[0-9]1,3\.)3[0-9]1,3\b
This is where Xshell's become an indispensable tool. By allowing users to define specific keywords and regular expressions with custom colors and styles, they transform a featureless text stream into a color-coded, highly scannable dashboard.
