Frequently Asked Questions
- What IP address format is matched?
- IPv4 dotted-quad notation — four groups of 1–3 digits separated by periods, like 192.168.1.1 or 10.0.0.254. Each match is listed on its own line in order of appearance.
- Does it validate that each octet is 0–255?
- No — the matcher is format-based, so 999.999.999.999 would also match. For log analysis this is rarely an issue since real logs contain valid addresses; sanity-check unusual results.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
