Hi Skeeve,

Could you please relay my query to the APNIC-TALK list ? I dont have the email address for them.
I am willing to participate on any current forum which discusses the address assignment recommendations.

In my opinion, stateless autoconfiguration is little justification (to start assigning /64s for end-customers) when it comes to the issue of address exhaustion which was the main driver to come up with a 128 bit address space. If we start assigning /64s to end-customers right from day-zero, we are effectively halving the whole 128 bit address space and making all the vital /64s unavailable for use in future.

We can always ask vendors to modify the stateless autoconfiguration algorithm and look into slightly more conservative addressing scheme.

And we all know how difficult it is to reclaim address spaces from customers once they have deployed them.

We are talking about assigning 2^64 addresses to potentially small-scale customers ?? I don't understand the justification there.

Randy Bush: Yes I have read RFC 6177 and I am mainly concerned about its recommendations of assigning /64s - some ISPs in Australia are now taking these recommendations and assigning even residential edge customers with a /64 IPv6 space (I found this out after participating in AUS-NOG conference and was alarmed by this).

I can be reached on the following:

Hi Usman,

This is a good question and worth discussing.  But, it should be discussed in perhaps the apnic-talk list, not the sig-policy list, which is for policy related discussion.

Let's take it over there, and let the discussion begin!

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.

Usman
