Test, validate and match regular expressions
This regex matches sequences of four dot-separated groups of digits, resembling IPv4 addresses. It does not validate the numeric range (0-255), so it may match invalid addresses like 999.999.999.999. Useful for quickly extracting or highlighting IP-like patterns in logs, text, or configuration files where basic matching suffices.
