Hi,

I don't know exactly the logic behind /64, but if you argue that /96 is enough for residential,

people can also argue 64bits or even 32bits is also more than enough for service network subnets,

in addition to that, the potential growth of subnets is not huge,

but the potential growth of devices type is unpredictable.

Regards

Terence

Hi,

I am trying to understand the reasoning and logic behind IETF/IANA's decision to recommend assignments of /64 addresses to residential CPEs ??
In my opinion, this would result in a lot of unnecessary wastage of IPv6 address space.

Can someone help me to point towards the drivers behind this thinking?

IMO a /96 IPv6 assignment to residential customers is more than enough.

regards

Usman
