If I recall correctly, ipv6 addresses beginning with 0::0:ffff are mapped 1-to-1 with ipv4 addresses.

  I’m mostly still annoyed about the colon. Come on, ip:port is a pretty widely used convention people! The number of parsing bugs I had to fix with the migration…

    On the plus side the schedule was reasonable, you had time since the 1990s :)

      The flip side is job security so it’s not all bad :)

    It is today, but what about at the time it was picked? Software from that era (e.g. telnet) take their hostname/service arguments as two strings (e.g. `telnet 127.1 ssh`). I believe ip:port comes from URLs, the RFC for which was published at the end of 1994, which is about the same time that v6 was being developed. So it's not clear that the fault isn't on the URL side, or on the side of software using URL conventions when they're not using URLs. Note that staying with "." wasn't an option, due to ambiguity with DNS. (Consider something like "2001.db8.3.4.5.6.7.be": is that an IP or a hostname under .be?)
