Ken Reaser: I am a Network Administrator and Technical Instructor. I teach CompTIA ITF+, A+, Network+, Security+, & CySA+. I also teach Microsoft MTA 98-366, 98-367, and occasionally teach the Microsoft server classes. My main specialty is the Security+ boot camps. I am developing these Blogs to help people prepare for the exams. In addition to the Blogs, I have a YouTube Channel (Komputers done Right). One of the main reasons for that channel was to teach IPv4 subnetting. My students have bugged me for the past few years to make the videos. There will also be How-to videos added very soon.
