Split an IP address into four separate values

Question

How do I split an IP address into four separate values?

Example if my ip is 192.168.0.1

Value1 = 192

Value2 = 168

Value3 = 0

Value4 = 1

Answer 1

For IPv4, each octet is one byte. You can use System.Net.IPAddress to parse the address and grab the array of bytes, like this:

// parse the address
IPAddress ip = IPAddress.Parse("192.168.0.1");

//iterate the byte[] and print each byte
foreach(byte i in ip.GetAddressBytes())
{
    Console.WriteLine(i);
}

The result of the code is:

192
168
0
1

Answer 2

If you just want the different parts then you can use

        string ip = "192.168.0.1";
        string[] values = ip.Split('.');

You should validate the IP address before that though.
