[arin-ppml] Why are ISPs allowed?

Q:  How do you eat an elephant?

A:  In small bites!

It's not impossible to upgrade 4K customers if you plan it and allocate
enough time.  However, realistically what your actually seeing here is
a political effort that should be supported.

All of the Linux-based DSL modems out there that are in production
have already had the R&D money spent to develop their firmware code.
Their manufacturers never planned or allocated funding to develop
IPv6 code for these devices.  What the Broadband Forum is attempting
to do is apply enough pressure to force these manufacturers to go back
and spend more money developing firmware updates for devices that have
already shipped out.  It's an admirable attempt and if it can get 1
or 2 manufacturers out there to develop firmware for some devices then
it's worth the effort.  I would for example like to see Netopia release
IPv6 firmware for the Motorola model 3347 DSL modem that Qwest is currently
shipping, and I don't think it would kill 2wire to release IPv6 firmware
for it's model 2701 that both Qwest and SBC have used.

At the least for the Linux-based stuff these manufacturers should be
prevailed on to release the firmware source so that the Linux community
can add in IPv6 support if it wanted to.  The DD-WRT community already
has a lot of experience doing this - and frankly, anything developed with
Linux is required to release source under the terms of the GPL anyway.

My feeling, though, is that what really is going to be needed is a
new generation of DSL modems with much faster processors that can
do stateful inspection, because after IPv6 we can't depend on the
pseudo-firewalling of a NAT to protect customer devices.

Just about all DSL modems in the field can be put into bridged mode
so that is always an option - to bridge them then put an IPv6 router
behind them.
