How to see if an IP address belongs inside of a range of IPs using CIDR notation?

Question

Here I have a static reference the ranges I need to check:

private static List Ip_Range = new List()
{
    \"12.144.86.0/23\",
           


        

Answer 1

For start, you should use that:

IPNetwork ipnetwork = IPNetwork.Parse("192.168.168.100/29");
Console.WriteLine("CIDR: {0}", ipnetwork.Cidr);

Output

CIDR: 29
