using IpMatcher;
Matcher matcher = new Matcher();
matcher.Add("192.168.1.0", "255.255.255.0");
matcher.Add("192.168.2.0", "255.255.255.0");
matcher.Remove("192.168.2.0");
matcher.Exists("192.168.1.0", "255.255.255.0"); // true
matcher.Match("192.168.1.34"); // true
matcher.Match("10.10.10.10"); // falseThe matcher uses two primary internal objects. The first is a Dictionary which acts as a faster cache. Success responses to Match will update this Dictionary. On Match requests, the Dictionary is checked first for a match. Behind the Dictionary cache, a list of Address objects are stored.
A lot of the internal matching code was adapted from: https://social.msdn.microsoft.com/Forums/en-US/c0ecc0de-b45e-4ca4-8d57-fc9babd4c221/evaluate-if-ip-address-is-part-of-a-subnet?forum=netfxnetcom
