Practice Your Subnetting

Sub.Net is a simple program that allows you to practice your subnetting knowledge. This is a great tool to study for your CCNET, CCNA, or any other networking text. Knowing your subnetting is a huge part of tests like these.

Sub.Net gives you a random ip address and asks for you to identify the network address, broadcast address, and the decimal version of the subnet mask.

PC Requiments:

  • Microsoft .Net 4.5
