Hi Steve,

Would you support the proposal if the lines allowing large IPv4
holders to skip the /48 level and go straight to /32 were removed?
That's the only place IPv4 is mentioned. Would you remove them
entirely and make everyone start with a /48 or would you replace them
with some other criteria that was not tied to IPv4 specifically?

Hi Larry,

As an ISP you probably already hold a /18 of IPv4 space. As a result,
you would be qualified for a /32 immediately under the proposed
policy. You would later be qualified for an additional /24 *without*
returning the /32 or renumbering any of your customers. Nothing in the
policy would ever require you to renumber out of either the /32 or the

If you bought another ISP's assets with another /32, you would have to
renumber those acquisition customers into your /32 in order to later
get the /24.

Does that affect your opinion any? Or would you still be opposed
because of the requirement to renumber out of space you acquired
through acquisitions?

Hi Ted,

No, we haven't plateaued. Router capacity is increasing and while I
haven't collected the data to prove a trend as a companion to my bgp
cost piece, I'm pretty sure the cost per announced prefix is slowly
coming down. However, the route count is increasing faster than the
cost per route is falling, so the overhead cost of the system as a
whole is going up.

Eventually. That's what the IRTF RRG is all about: identifying those
advances. But it won't happen in a useful time frame for a 2009
discussion of IPv6 address policy.

Blurred nothing. I kicked the it to curb. This proposal makes no
distinction whatsoever between ISPs and anyone else. And eliminating
preferential treatment based on a frequently artificial distinction
doesn't disturb me at all.

What complexity? You're multihomed? You qualify. Done.
