Regex Editor & Tester

This regular expression matches standard IPv4 addresses by looking for four sets of 1 to 3 digits separated by periods. It uses word boundaries to ensure it does not match partial numbers within longer strings of digits. While it effectively identifies the standard format of an IP address, it does not strictly validate that the numbers fall within the valid 0-255 range. It is best suited for quick extraction tasks in log files or text documents.
