I just started a job where I’m in way over my head on the networking and specifically the subnetting side. Having almost no drawings or documents to help me figure out how the 4 or 5 networks communicate, this video has really helped me understand it some more and given me some tools to figure this mess out. Your video editing really helped me to visually comprehend what the instructions were saying and explaining. Much appreciated!!
