Completely agree with all you've said here about how DOCSIS works.
Several cable operators (at least) are working to make it so that DHCPv6
assigns business customers the same IPv6 prefix every time. Yes, it's
DHCPv6 instead of static configuration, but I think it works.
Additional question, though:
Randy said "at&t business 1g fiber going into an Arris"
As fiber, it'll be PON. If it were a traditional cable company, I'd
guess DPOE (DOCSIS Provisioning Over Ethernet).
Except it's AT&T, and I don't know if they're provisioning DOCSIS over
their fiber; I would think it's GPON, using the same infrastructure as
their U-Verse product (fiber to the curb, DSL to the home). That used to
be PPPoE and not DHCP, but my information may be out of date.
