How does Golang determine whether it is an IP address?

Golang's method to determine whether it is an IP:

We can determine whether it is an IP by determining whether it is a legal IP address. In go language, you can use the net package to check whether it is a legal IP.

Implementation code for judging whether the IP is legal in the go language:

package main

import (
     "net"
     “fmt”
)

func main() {
   
    ipv4 := "12.56.30.88"
    // ParseIP 这个方法 可以用来检查 ip 地址是否正确，如果不正确，该方法返回 nil
    address := net.ParseIP(ipv4)  
    if address == nil {
         fmt.Println("ip地址格式不正确")
    }else {
         fmt.Println("正确的ip地址", address.String()) 
    }
     
}

The ParseIP method can check the IP addresses of ipv4 and ipv6.
