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.
