IPv6 just turned 30

And it still has not taken over the world, according to the Register. I would love it if it had: a truly peer-to-peer internet is a wonderful dream.

The article has been discussed at Hacker News, and while one could of course find the usual comments about

addresses being too long and unreadable
globally routable addresses reduing security by taking away NAT
there being too many addresses

there were also a few insightful bits scattered around the comments.

One aspect of the smallest network prefix necessary for SLAAC /64 I have not thought about before is that it prevents ISPs from charging customers by-device. It sounds ridiculous... until you realise that this probably is what corps would love to be able to do.

A bonus: a link to ULA ie, Unique Local Address, registry. Browse through registered and have a laugh at some of the names. I found it funny that some prefixes are registered under names that are basically Bob, or John Doe, or Max Mustermann.
