  • The reason IPv6 was originally added to the DOCSIS specs, over 20 years ago, is because Comcast literally exhausted all RFC1918 addresses on their modem management networks.

    My favourite feature of IPv6 is networks, and hosts therein, can have multiple prefixes and addresses as a core function. I use it to expose local functions on only ULA addresses, but provide locked down public access when and where needed. Access separation is handled at the IP stack, with IPv4 it’s expected to be handled by a firewall or equivalent.
