[noipv6]

> It was relevant then -and it is relevant now- because there are good lessons in how to migrate from thing A to thing B, even if some of the then-missing necessary bits are in place now.

it's irrelevant now because there are smoother approaches to migrating to future-proofed networks than existed at the time. the fact that it persists on the internet, unamended, to be regularly presented (two decades later) as some semblance of current realities of the challenges to ipv6 deployment is a disservice to the internet.

> Still, it's almost certainly the case that DJB's rant had no real effect, and that the necessary steps were bound to be taken as the cost of sticking with IPv4 rose.

i would maintain that "ipv6mess" had a NEGATIVE impact on ipv6 adoption overall, as people who saw djb as a tech god accepted his word as gospel, despite it fundamentally being a crybaby rant, & proliferated the misconceptions & opposition therein.

the fact that he explicitly rejected ipv6 patches to qmail & djbdns (resulting in a fork to at least qmail) should not be understated - he didn't just complain about ipv6, he actively sought to undermine its adoption.
