How To Make A IP Analyzer In VB.NET

This is a good one but its a in console but i hope you will like it and it has not alot code . the program works like when you enter a IP address and press enter key in your keyboard then you will see the class of the ip address and subnet mask and IP binary and network address and at last broadcast address so i hope you will like the features and dont forget you can also make alot features for this if you made anything dont forget to comment it ok lets begin making it now make a console project and name it and when it loading successful then add this code down

Imports System.Net
Module Module1

now debug and try it
