Professor Messer - Seven Second Subnetting

Subnetting with (almost) zero math. In seven seconds or less! This is the subnetting procedure I use when taking a certification exam. If you're looking for a way to subnet that is fast, accurate, and simple, this is for you. I highly recommend that you understand the math behind the subnetting process before watching this video. There's a lot more to know about subnetting than what's in this video! You may want to reference my other videos that discuss binary math and binary-based subnet calculations: Binary Math: https://www.youtube.com/watch?v=QxGTQVZp77U IPv4 Addresses and Subnetting: https://www.youtube.com/watch?v=_bn0CF5zqvo
