No.

That's what DHCPv6 is for.

In terms of external DNS, most routers support dynamic DNS with several
protocols; but it's normally a very simple operation to update your
AAAA records manually.  Or even by a shell script, like I run on my
Ubuntu and RISC OS boxes, to automate it.  Most domestic users have
very few internet-facing IP addresses and therefore very few DNS entries
to update, so the task doesn't comsume much time.
