Find IPv4 in Javascript

Explication

This regex pattern matches IPv4 addresses. It looks for sequences of 1 to 3 digits followed by a period, repeated three times, and ending with another sequence of 1 to 3 digits. The \b ensures that it matches the whole IPv4 address and doesn't capture partial matches within longer strings.
