Where to start?    I started years ago working on my Cisco CCNA and CCNP certifications.  I installed a Cisco Virtual Lab (VIRL).  Above you will see all the configurations I made on IPv4 and IPv6.   I was able to get a TFTP server working on my workstation to copy out the configurations in both IPv4 and IPv6.   I created my own IPv6 addressing scheme and used it.  

AT&T gave me one /64 IPv6 PD.  After 3 years of waiting for Gig Fiber from them, I gave up.   June 2021, I switched to Comcast Internet.   I was able to get a /60 block.
