+1 to ULA should go extinct. Why do they even exist? How have they helped global native IPv6 adoption (without NAT66/NPTv6)?
+1 to GUA being the default standard if IPv6 is called into play. +1 to using GUA on "private" networks – future-proofed with GUA for future *inter*connectivity*.* +1 to IPv6 being about the number of networks (/64s) and not the number of "hosts"; the latter is, without a doubt, IPv4-centric. *--* Best Regards Daryll Swer Website: daryllswer.com <https://l.shortlink.es/l/a1abea4cf890b4fe45d3ca3253ffe607875c37ed?u=2153471> On Mon, 29 Jun 2026 at 23:16, John Osmon <[email protected]> wrote: > > Current qualifications for ARIN to assign an IPv6 /48 block for > > off-Internet use is roughly: > > > > 1.
