Basically what the title says. Here’s the thing: address exhaustion is a solved problem. NAT already took care of this via RFC 1631. While initially presented as a temporary fix, anyone who thinks it’s going anywhere at this point is simply wrong. Something might replace IPv4 as the default at some point, but it’s not going to be IPv6.

And then there are the downsides of IPv6:

  • Not all legacy equipment likes IPv6. Yes, there’s a lot of it out there.
  • “Nobody” remembers an IPv6 address. I know my IPv4 address, and I’m sure many others do too. Do you know your IPv6 address, though?
  • Everything already supports IPv4
  • For IPv6 to fully replace IPv4, practically everything needs to move over. De facto standards don’t change very easily. There’s a reason why QWERTY keyboards, ASCII character tables, and E-mail are still around, despite alternatives technically being “better”.
  • Dealing with dual network stacks in the interim is annoying.

Sure, IPv6 is nice and all. But as an addition rather than as a replacement. I’ve disabled it by default for the past 10 years, as it tends to clutter up my ifconfig overview, and I’ve had no ill effects.

      You don’t remember a ipv4 either

      172.26.0.37. That’s the IP of the frggin’ Kyocera printer that takes way too many clicks to configure for every new user. And we get new users… about bi-monthly, which you’d think isn’t that bad, but that interface is downright kafkian.

      I don’t remember the router’s IP. I more often than not don’t remember the DNS servers. But that thing… that thing I remember.

          Printers should be renamed “Tree-taggers” or something similar. Give it a name that makes the concept sound as bad as the implementation.
