Conversion IPv6 to long and long to IPv6

Question

How should I perform conversion from IPv6 to long and vice versa?

So far I have:

    public static long IPTo         


        

Answer 1

You can also use java.net.InetAddress
It works with both ipv4 and ipv6 (all formats)

public static BigInteger ipToBigInteger(String addr) {
    InetAddress a = InetAddress.getByName(addr)
    byte[] bytes = a.getAddress()
    return new BigInteger(1, bytes)
}
