I'd like to encourage people to use prefix-hint=::/48. The router should accept the /60 and deal with it, but it's better to have Comcast's logs show that you requested a proper full-size prefix. I'm almost afraid to ask about the phrase "add-default-route=yes" in the dhcp-client configuration. That seems wrong on the face of it since you should be getting your routing information from RA and not DHCP. > In the case of Comcast (and anecdotally ISC DHCP) - You'll either need > to wait out the the lease time (4 days) or ask Comcast to nicely clear > out your /64 lease manually.
