Example 9 is broken about ipnetwork

[lduchosal]

Dear BigPacket,

Thanks for your question. There are 2 methodes that behave almost identically :

IPNetwork.TrySupernet
IPNetwork.TryWideSubnet

TrySupernet will merge only consecutive subnets (192.168.0.0/24 + 192.168.1.0/24 = 192.168.0.0/23)
TryWideSubnet will find the smallest subnet that can contains the subnet in argument (192.168.0.0/24 + 192.168.10.0/24 = 192.168.0.0/20)

    [TestMethod]
    public void When_TrySupernet_192_168_0_0_cidr24_add_192_168_10_0_cidr24_Then_Should_Invalid()
    {

        IPNetwork network = IPNetwork.Parse("192.168.0.0/24");
        IPNetwork network2 = IPNetwork.Parse("192.168.10.0/24");

        bool supernetted = network.TrySupernet(network2, out var ipnetwork);
        Assert.AreEqual(false, supernetted);


    }

    [TestMethod]
    public void When_TryWideSubnet_192_168_0_0_cidr24_add_192_168_10_0_cidr24_Then_Should_Invalid()
    {

        IPNetwork network = IPNetwork.Parse("192.168.0.0/24");
        IPNetwork network2 = IPNetwork.Parse("192.168.10.0/24");

        bool wideSubnetted = IPNetwork.TryWideSubnet(new[] { network, network2 }, out IPNetwork ipnetwork);
        Assert.AreEqual(true, wideSubnetted);
        Assert.AreEqual("192.168.0.0/20", ipnetwork.ToString());

        Console.WriteLine("Network : {0}", ipnetwork.Network);
        Console.WriteLine("Netmask : {0}", ipnetwork.Netmask);
        Console.WriteLine("Broadcast : {0}", ipnetwork.Broadcast);
        Console.WriteLine("FirstUsable : {0}", ipnetwork.FirstUsable);
        Console.WriteLine("LastUsable : {0}", ipnetwork.LastUsable);
        Console.WriteLine("Usable : {0}", ipnetwork.Usable);
        Console.WriteLine("Cidr : {0}", ipnetwork.Cidr);

    }

Hope this helps.
