FYI - DHCP-PD is now working better in RouterOS 6.5
Prefix length hints are now available (CLI) only.
/ipv6 dhcp-client add add-default-route=yes interface=<wan interface>
pool-name=dhcp-pd \
prefix-hint=::/60
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. Release/renew doesn't release your current
DHCP lease. I was getting A /64 and /60 (/64 had a preference of 255)
before Comcast removed the /64 lease manually.
