Bitvantage.InternetProtocol.NetworkPrefixLookup.IPNetwork2

Longest-prefix-match lookups over IPNetwork2 networks from the IPNetwork2 package. Given an address, a lookup finds the most specific stored network that contains it and the value stored with that network.

dotnet add package Bitvantage.InternetProtocol.NetworkPrefixLookup.IPNetwork2

Or from the NuGet Package Manager console:

PM> NuGet\Install-Package Bitvantage.InternetProtocol.NetworkPrefixLookup.IPNetwork2

using System.Net;
using Bitvantage.InternetProtocol.NetworkPrefixLookup;

var zones = new IPNetwork2Lookup<string>
{
    { IPNetwork2.Parse("192.168.0.0/16"), "office" },
    { IPNetwork2.Parse("192.168.10.0/24"), "lab" },
};

// the most specific stored network that contains the address
if (zones.TryGetMatch(IPAddress.Parse("192.168.10.7"), out var network, out var zone))
    Console.WriteLine($"{network} -> {zone}"); // 192.168.10.0/24 -> lab

// a read-only copy with faster lookups
var snapshot = zones.Freeze();

IPNetwork2Lookup<TValue> and its frozen form have the same members as the core package's lookups for System.Net.IPNetwork: lookups from addresses, integers and bytes, queries about networks, batches and frozen tables. The main README describes them and their performance.
