This library is designed to optimize the lookup of an IP address in a set of IP Ranges. It supports both IPv4 and IPv6 addresses. It provides methods for checking if an IP address is a part of Public IP Ranges for M365 endpoints.

Usage Examples

  1. To check if an IP address is present in Public IP Ranges.

Eg: IPSearch ipSearch=new IPSearch(); bool result=ipSearch.Contains(""); //false

  1. To check if an IP address is present in a list of Subnets (CIDR). 

Eg: List<string> input = new List<string> () {"", ""}; IPSearch ipSearch=new IPSearch(input); bool result=ipSearch.Contains(""); //true

  1. To check if an IP address is present in the provided Subnet CIDR list and get the corresponding T value of the range. 

Eg: List<Tuple<string, string>> input = new List<Tuple<string, string>> () { Tuple.Create ("" ,"abc"), Tuple.Create ("" ,"xyz") }; IPSearch<string> ipSearch=new IPSearch<string>(input); Tuple<bool,string> result=ipSearch.Lookup(""); //(true,"abc")
