I want to use my router's kresd for ipv6, but I don't have a static IP address. is this where I should go for those fe80 addresses, assigning each interface on my router a static fe80 address and filling that in for RDNSS?
or fc00 I guess
or fd00 I guess

I guess? In theory, what _should_ happen is your router notices a change in upstream addr, and modifies its downstream advertisements. All clients reconfigure, and all is well.
in practice though, I don't know of any v6 config server that doesthat.

gchristensen: I'd go with static ula addressing in addition to the dynamic global ones

danderson: in theory, yeah, but tragicaly not in practice it seems :P
hexa-: cool, thanks!
I suppose I should probably randomly generate the IP instead of fd00:5:4::1
yep, router advertisment reconfiguration and timeouts are tough to get right
gchristensen: it depends on how much collision resistance you need
well I have about 10 hosts and am unlikely to go through an acquisition or merger with another household
if you want to route that ULA network within DN42 for example you probably want to randomly generate it

your fe80 will also be stable assuming you don't change your network ports around. i haven't set it up yet, but this is one of reasons i have a /56 on my linode to tunnel back to home for v6 that doesn't change with prefix delegation. and also because at some point in february, spectrum killed my inbound ipv6 access.
