Ip address Regular Expression matching method, ip address Regular Expression matching

A Regular Expression (Regular Expression) is a concept in computer science. Regular Expressions use a single string to describe and match a series of strings that conform to a certain syntax rule. In many text editors, regular expressions are usually used to retrieve and replace texts that match a certain pattern. Many programming languages Support string operations using regular expressions. In many text editors, regular expressions are usually used to retrieve and replace texts that match a certain pattern.
