alt Hacker News> Other than ... lack of DNS integration...
I'm confused. What do you mean by this? Does dnsmasq not put the names of DHCPv6 clients into its hostname database? If ISC DHCPd is commanded to update DNS, does it only update for DHCP clients and not DHCPv6 clients?
They probably mean that when using SLAAC - I guess the easiest way to get ipv6 connectivity - there is no equivalent to the way you can update DNS the way it would work with DHCPv4 or DHCPv6.
You pointed out one way - justuse DHCPv6, but that looses some of nice SLAAC properties.
A different way is to run mdns and let the devices announce their own hostnames.local.
Different tradeoffs, but in practice not too difficult to get to work.
I guess one could even do both...
