Agreed. Though I wonder if ipv6 will ever displace ipv4 in things like virtual networks (docker, vpn, etc.) where there's no need for a bigger address space
I'm using IPv6 on Kubernetes and it's amazing. Every Pod has its own global IP address. There is no NAT and no giant ARP routing table slowing down the other computers on my network. Each of my nodes announces a /112 for itself to my router, allowing it to give addresses to over 65k pods. There is no feasible limit to the amount of IP addresses I could assign to my containers and load balancers, and no routing overhead. I have no need for port forwarding on my router or worrying about dynamic IPs, since I just have a /80 block with no firewall that I assign to my public facing load balancers.
Of course, I only have around 300 pods on my cluster, and realistically, it's not really possible for there to be over 1 million containers in current kubernetes clusters, due to other limitations. But it is still a huge upgrade in reducing overhead and complexity, and increasing scale.
I use ipv6 when possible but it's rarely possible. I've never had home internet that was ipv6 ready enough for my wan address when googling "what's my ip" to be something besides an ipv4 number.
Could I get ipv6 over otherwise non ipv6 compatible hardware using a vpn?
You're probably in a country that got a ton of allocations in the 90s. If you came from a country that was a little late to build out their infrastructure, or even tried to setup a new ISP in just about any country, you would have a much harder time.
Cisco as a client tried to force ipv6 for their managed service and after an entire quarter of attempting to resolve it, we actually disabled it for their virtual address per their request. IPv4 has issues and IPv6 promises solutions, but it's not a stable platform yet. This appears ignorant but is based on truth. IPv6 is also eventually going to hit exhaustion with the frequency we spin up virtual machines, it's okay to skip a bad generation.
Ipv4 is one of those things that works awesome, is simple, and is a victim of its own success. Ipv6 is just complicated bloat of a standard. Cool features, but nobody implements them, so useless.
In 30 years, probably useful. Until then, I'm not giving up Ipv4.
