An embarrassing admission, but one that is potentially useful for this conversation: I have a Cisco CCNA cert that I got in 2009 but never used. (Got a job that didn’t put most of the knowledge to use, and the cert collected dust.) IPv6 was on the exam. I’ve forgotten all about how to use it. For me it is just not as intuitive. Maybe others think the same, slowing adoption? I didn’t find it intuitive when studying for the exam, but I got it enough to pass. Basic networking knowledge I still have. I can tell you how to set up a DHCP and DNS server, and how NAT works on your router. I can tell you about ARP tables, VPNs, VLANs, firewalls, and subnets. I can’t begin to tell you about the equivalents on v6. Maybe I’m just getting old. Maybe it would come to me once I started using it again. Or maybe it’s just not as intuitive.
