Regex Tester & Validator

Matches the literal text 'IP ' followed by one or more word characters, using a negative lookahead to exclude cases where the next word is 'Address' or 'address'. This is designed for find-and-replace scenarios like expanding abbreviations (e.g., turning 'IP config' into 'IP address config') while avoiding double 'address' in phrases that already say 'IP Address'. Commonly useful in documentation cleanup and text normalization.
