It has been a while since I did routing and switching lab, lots of focus and energy has been put on learning security, security is exciting and huge…in fact more exciting than routing and switch lol. However at the moment networking is still my core skill to earn a living hence I got to keep up, refresh myself and stay current.
I have known about ipv6 when I was pursuing CCNP, did a few labs but did not know how to do subnet, lol….Wow…a network engineer does not know subnet? what a joke!
Subnetting ipv6 addresses was surprisingly easier than ipv4.
This is very good reference:
