Regex Generator

Generated pattern for strict validation including CIDR & Port.

^(?:(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])\.){3}(?:25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9]?[0-9])(?::[0-9]{1,5})?(?:/(?:3[0-2]|[12]?[0-9]))?$

This pattern validates CIDR prefixes (0-32) and port numbers (1-65535). Use it in languages like JavaScript, Python, or Java for robust string validation.

Did You Know?

Dotted-Octal IPs: Linux tools sometimes accept IPs in octal format (e.g., 0300.0250.001.001), but this is often considered a security risk as it can bypass some simple filtering systems.

Hex IPs: Some browsers will resolve dotted-hex IP addresses like 0xC0.0xA8.0x01.0x01 just as they would decimal ones.
