assert myIp == true

let myIp = isValidIp4("192.168.1.10", "lan")
assert myIp == true

let myIp = isValidIp4("192.168.1.10", "private")
assert myIp == true

Check if given string is a public IP address:

Just pick whatever keyword you personally prefer.

let myIp = isValidIp4("111.12.1.10", "public")
assert myIp == true

let myIp = isValidIp4("111.12.1.10", "wan")
