Subnetting can be a challenge to learn initially. Instead of trying to write yet another lesson on subnetting I thought I would just include a few good references and create a lab where you can test your skills. I will urge you to watch different YouTube videos on subnetting and read different materials on the topic because it's always good to learn it from different perspectives. Especially on the topic of subnetting. And practice, practice, practice! At some point it will click and everything will be clear in the world of subnetting!
Of course, feel free to ask any subnetting questions you might have here. I'll update the study notes with the best tips and guides.
- Review Cisco's subnetting best practices
- Practice, practice, practice
- Do your own subnetting long-hand and check your answers here: http://subnet-calculator.org/ (it's the best calc I've found so far)
- Watch YouTube videos on subnetting. This one is succinct and clear: https://www.youtube.com/watch?v=hb2yTNT2rBU
