Re: IPv6 prefixes longer then /64: are they possible in DOCSIS networks?

* Dmitry Cherkasov:

It is commonly agreed that /64 is maximal length for LANs because if
we use longer prefix we introduce conflict with stateless address
autoconfiguration (SLAAC) based on EUI-64 spec. But  SLAAC is not used
in DOCSIS networks. So there seems to be no objections to use smaller
networks per cable interfaces of CMTS.

As far as I understan the IPv6 address architecture, if the network
prefix is longer than /64, you're not running Unicast IPv6.
