Test, validate and match regular expressions
This regular expression matches basic IPv4 addresses consisting of four sets of one to three digits separated by dots. It uses word boundaries to ensure the IP address is isolated from other text. While useful for extracting IP-like patterns from documents and logs, it does not validate the numeric ranges (0-255), meaning it will match invalid IPs like 999.999.999.999. It is ideal for quick extraction rather than strict validation.
