Should probably fix that given we’ve been out of IPv4 for over a decade now and v6 is only becoming more widely deployed
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 wish everything would just default to a unix socket in /run, with only nginx managing http and stream reverse sockets.
Wait, but if you have, for example an HTTP API and you listen on a unix socket in for incoming requests, this is quite a lot of overhead in parsing HTTP headers. It is not much, but also cannot be the recommended solution on how to do network applications.

Really? Haven’t had trouble allocating new VPSs with IPv4 as of late…
It is incredible to me how some people think they make themselves look smart by wearing their willful ignorance like a crown.
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.

Top-tier trolling right here.
I’m sorry but how? We have appliances with dockerfiles, micro containers for remote controls, extensive botnets of virtual machines, centuries in the future when we have expanded into the solar system and trillions of humans all having millions of unique applications with addresses, it’s inevitable to hit a finite number. When every square meter of smart road has an routable address; we will likely be rewriting networking anyways. The only players pushing IPv6 transition are networking companies because a new standard requires new hardware.
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.
Wait this is real?
No, it’s an edit. I linked the original in the post text. If you can’t access it for some reason, here’s a transcript:
