    Now that you've clearly stated that this "It is expected to stall and fall rapidly in the near future"

    Again, not the total number of IPv6 users, but the adoption rate. Meaning the number of "new" IPv6 users per month.

    I speak fluent sarcasm and broken logic. | I would agree with you, but thæn we’d both be wrong.

  • Even ColoCrossing is rolling out IPv6 now. ColoCrossing. Sorry you don't like IPv6. Nothing new to see here.

  • My ISP still refuses to give me IPv6

    My legacy server with a top level DC is still not receiving IPv6. Only new orders get IPv6...
    My cheap server provider is providing IPv6 only on mid range servers...

    Your top level DC is waiting for you to pay for the upgrade.

    Well, ya.. I mean I am paying only $140 per year for my server for the last 6 years, while their lowest end servers starts at $65/month (after a 50% discount on black friday offers...)

  • It’s moving fast because ARIN finally started aggressively reclaiming legacy blocks from defunct companies (the "use it or lose it" audits).

    But heads up: Be careful what you wish for. "Reclaimed" space is often radioactive.

    A lot of these blocks were sitting dormant for years, which means they were likely hijacked by spammers or have stale geolocation data pointing to random countries. I’ve seen people get a "fresh" /24 from the waitlist, only to spend the next 6 months fighting Spamhaus and trying to convince Google they aren't a bot farm.

    If you are just playing around in a homelab, the waitlist is fine. But if you are running production (especially email), the "Waitlist Lottery" is dangerous. You are usually better off leasing a scrubbed block where the reputation is guaranteed, rather than inheriting someone else's mess.

    A dormant, unused, block of IPs can be simply used by an unauthorized party?

    I fully run IPv6 in my network with NAT64 for those websites that are still legacy only. As devices become more modern and updated, they straight up refuse to get an IPv4 as they respect DHCP 108.

    From my side i get full transparency on what's happening on my network, everybody gets their own public IP subnet (which is still firewalled, of course) and i don't need to juggle around and care about addressing schemes, reservations or static IPs since SLAAC means everybody will just pull a static IP in a truly stateless way.

    You're welcome to disable IPv6 as soon as possible on every device you own or network you manage out of spite but really there is no reason at all to do that except ignorance
