Regex Editor & Tester

This regular expression matches basic IPv4 addresses by finding four sets of 1 to 3 digits separated by dots. Because it only checks the number of digits and not the actual value, it serves as a simplified or "short" pattern that will match invalid IPs like 999.999.999.999. It is ideal for quick text extraction or scenarios where loose pattern matching is preferred over strict 0-255 range validation.
