Subnetting by hand...yes! This is really helpful for those studying for the CompTIA Network+ exam, and for those who are about to go on a technical interview.
Sometimes, you just don't have any paper to do the subnetting math with, but you always have your hands with you. Learn to answer subnetting questions quickly by using hand in this video.
This video comes from my CompTIA Network+ course available at DionTraining.com and on Udemy. I hope this helps some of you who are struggling with subnetting.
