[AusNOG] SPAM-MED: Re: Data Retention and CGNAT - educational exercise

[Scott Howard]

It is *exactly* what Comcast has done.

They have actively moved people from DOCSIS 2.0 to DOCSIS 3.0 modems (as
required for IPv6) under the excuse of better performance (true in some
cases, but not all).  They actually EOL'ed support for my DOCSIS 2 modem on
the grounds that it would not provide maximum performance after some recent
network upgrades, despite the fact that the plan I was on was well within
what DOCSIS 2.0 provides.

Their DOCSIS 3.0 modems have IPv6 enabled by default, as does basically all
of their cable network.  I don't have one of their routers, but my
understanding is that they are gradually rolling out upgrades to those that
have IPv6 enabled by default too.

I am a beta tester for one of the major CPE vendors, and have been told by
one of their engineers that Comcast is requesting all future cable
modem/routers from them have IPv6 enabled by default, and that's definitely
the case for the modem/router I'm currently testing.

All of this without 99.99% of their customers even knowing what IPv6 is,
let alone knowing that it's enabled on their network.

Of course, nobody is suggesting they will be turning off IPv4 anytime soon,
but if/when they do need to implement CGN you can guarantee they are going
to need a LOT less hardware to implement it than they would have if they
were not so far ahead of the curve on IPv6.
