State of IPv6-Only on LINUX: Do you need a CLAT?

Today I’m taking a look at the state of IPv6-only on Linux. How far can you get with DNS64 alone? If you need a clat, how easy is it to setup clatd? And, what are some other options the Linux community has for dealing with legacy IPv4?

  • I really hope we'll get a proper ePBF solution, maybe at the connect level like the dynamic library ?

  • always funny when people wander into a forum asking why their online games dont work when they disabled ipv6 for their entire system/network

  • seems that ipv6 is stuck in same situation as Linux for desktop. It's viable but has lots of complications and thigs you need to figure out, substitute, compromise. Also, there always people who say this year will be Linux desktop year, but it never happens.

  • How on opnsense to enable traffic on IPv6 if the ISP does not support IPv6? I know that I can get an IPv6 address from TunnelBroker net, but I don't know what to do next.

  • Have you seen many people who run IPV6 islands, without public ipv6 connectivity?

  • People really ned to learn IPv6. It's super easy.

    Unfortunately, the only problem I've been having is that Proxmox VE 8.2 won't accept router advertisements, even when set to 2. It also won't accept the reserved IPv6 address when using DHCPv6, either. So I don't know what's up with Proxmox, lately. They seem hostile to using it with a dynamic prefix, for some reason.

    One problem keeping me on dual stack is the fact that my switches only support v4, and I would have no way to reach the switch webportal without v4.

  • My new fiber provider Allline promised public ipv4 but after connecting to it it refuses to disable cgnat and give dynamic public ipv4, as well as, it does not have ipv6 at all.😡

    It is the only fiber internet provider in my area, I have used 4G one before, it used CGNAT and blocked IPv6 incoming connections and was unstable 16-150mbit/s as opposed to new evil one that is constant 200mbit/s.

  • your displays shake so much i get anxious while watching ur videos.
    Very cool content despite that tho!

  • Did you happen to watch the stream of NetUK1 by any chance…?

  • The video that I have been waiting for.
    Thanks apalrd.
