and wonderfully again we baked in those classes in the
hardware/software! :) I think it'd be nice if we had the option to
build networks (ipv6 ones) and supply customers with what they need,
but lots of engineering/design time went into making a lot of
decisions for us :( So, you can't expect RA to work with prefixes <>
64 bits, but you can't expect RA to do everything we get with DHCP
anyway, so maybe that's "ok" ?
