Matching method of IP address regular expression

This article mainly explains "the matching method of IP address regular expression". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the matching method of IP address regular expression.

Regular expressions (Regular Expression, often abbreviated as regex, regexp, or RE in code) is a concept in computer science. Regular expressions use a single string to describe and match a series of strings that conform to a syntactic rule. In many text editors, regular expressions are often used to retrieve and replace text that matches a certain pattern. Many programming languages support string manipulation using regular expressions. In many text editors, regular expressions are often used to retrieve and replace text that matches a certain pattern.
