One of my ISProviders is TWC. If you don't use DHCPv6, what you
end up is the link-local address for each interface (which you get
anyway), and a default route to the link-local address of the TWC
router (through RA's), which is not useful if you don't have a real
IPv6 address on any of your interfaces.

This made things work very slowly, because everything tried IPv6
first because of the default route (until it timed-out).

On the bright side everything works if you run dhcpcd, and you get
a delegated /64 too for your internal network.
