IP Address Extractor
Find valid IPv4 and common IPv6 address forms in logs or notes.
How IP Address Extractor works
IP Address Extractor handles valid dotted IPv4 addresses and full or double-colon-compressed IPv6 forms from surrounding text instead of returning every number-and-colon fragment. IPv4 candidates must contain exactly four decimal octets no greater than 255. IPv6 candidates allow hexadecimal groups, one compression marker, and at most eight expanded groups. The IP Address Extractor exposes its text containing addresses controls so this particular convention stays inspectable instead of hiding behind an unexplained preset.
The default log line returns 127.0.0.1 and 2001:db8::1, while removing the sentence-ending period from the second candidate before validation. Operators can pull addresses from diagnostic output for comparison, allowlist review, or redaction without sending logs to a remote parser. The IP Address Extractor presents a deterministic plain-text result that can be copied and compared with the worked value before it enters another workflow.
Limits and private processing
The extractor does not resolve hosts, identify owners, or support IPv4 embedded at the tail of an IPv6 address. It only validates the local text form. The IP Address Extractor performs its complete operation locally in your browser; neither the source text nor its settings are uploaded, stored remotely, or sent through an external request.
