I recently passed the CCNA again and they really spend a lot more time on IPv6 compared to 15 years ago. It inspired me to go all in this time and configured my home network with a PD allocation from my ISP. I also came up with some fun labs and even got a IPv6 sage T-shirt from Hurricane Electric.
Any recommended courses? I'm a SWE and never felt compelled for the CCNA but my intersection with networking-related problems seems to continuously increase and I would like to up my game before getting in over my head at work.
Did you have to do anything special to get the t shirt? I got the sage cert ages ago and they never sent my shirt...
