As one of the IPv6 zealots talking about anything but a /64 for end =
sites, I
can assure you that I am talking about it for residential class service
not business class.
Your tech density may be above average for today, but, you lack vision
for the future.
Imagine a future where devices form autonomous network segments
and negotiate prefixes and routing for those segments in a semi-
or fully- autonomous fashion.
The appliance net in the kitchen will be managed by a router.
The RFID tags on the products in your fridge and your pantries
will form autnonous subnets with routers embedded in the
fridge and pantries. Each of your home entertainment clusters
will likely form its own subnet.
Even today, it is not uncommon for a residential gateway to support
at least five segments:
1. External WAN segment shared with ISP
2. Internal wired network
3. Internal wireless network
4. "DMZ" segment
5. Guest wireless network
Seriously, it's important that we do not limit our IPv6 thinking by
our IPv4 mindset. The future is not the present and we will see
much more advanced capabilities in the residential world
going forward if we allow it to happen.
