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.
