[plug] PLUG: Talk on IPv6 in March

[Adrian Woodley]

My understanding is that iiNet's ADSL hardware lacks IPv6 support.

Internode are still using the PPPoE model, which transports the PPP 
session back to a BBA/BRAS in the core network. The BBA/BRAS handles 
IPv6 over PPP, and all the DSLAM hardware sees is a stream of ethernet 
packets.

iiNet's IPoDSL relies on the DSLAM hardware to hand out IP addresses to 
clients, from within the exchange. This hardware doesn't yet have IPv6 
support, hence the need to use 6RD.

I'm not intimately familiar with iiNet's current deployment, but it may 
be possible to drop an IPv6 router into each exchange which is able to 
hand out IPv6 prefixes to clients, over DSL. This model hasn't been 
deployed in Australia yet, so would be new to both iiNet and Internode. 
I'm not sure if they're even looking into it at this stage or not.

Personally, I'd like to see them deploy a proper IPv6 Broker service. 
This could allow the static assignment of prefixes to individual 
accounts, removing the problem of network prefixes changing as IPv4 
addresses change (on re-connection). Unfortunately, this would be a more 
complex solution from a CPE perspective, although there exist good 
tunnel clients for all the major OSs. As far as over-heads are 
concerned, the packet structure is the same and the hardware 
infrastructure would be very similar, so performance is likely to be 
comparable to the existing 6RD service. Again, I don't believe they're 
actually looking into this yet.
