How to sort list of Ip Addresses using c#

Question

I've a list of IP addresses as follows

192.168.1.5 69.52.220.44 10.152.16.23 192.168.3.10 192.168.1.4 192.168.2.1 

I'm looking for such a way to sort this list to match the below order

10.152.16.23 69.52.220.44 192.168.1.4 192.168.1.5 192.168.2.1 

Answer 1

This might look as a hack, but it does exactly what you need:

var unsortedIps =     new[]     {         "192.168.1.4",         "192.168.1.5",         "192.168.2.1",         "10.152.16.23",         "69.52.220.44"     };  var sortedIps = unsortedIps     .Select(Version.Parse)     .OrderBy(arg => arg)     .Select(arg => arg.ToString())     .ToList(); 

Answer 2

You can convert each IP address into an integer like so ...

69.52.220.44 =>  69 * 255 * 255 * 255 + 52 * 255 * 255 + 220 * 255 + 44 

Then sort by the integer representation.
