Re: [Idr] new ID on expansion of private use ASN range

Hi Jon,

I have read your draft few days back and support adopting it as an IDR 
WG doc.

However I have one question/suggestion ...

Perhaps you recall some debates on the topic of reserving some address 
chunk like 1918, but only for operator's use.

Here with private AS numbers we actually are facing the same issue 
today. Flat space introduces a bit of a difficulty when both my internal 
ASes (example: data centers) as well as my customer's ASes use the same 
private as number.

This mandates the knobs like as_override or allowas_in to be applied on 
all address families.

The simplest way to solve it would be to define two blocks of 4 octet 
private AS numbers .. One for multi-as operators and one for stub 
networks. Maybe we could do the same for 2 octet AS numbers too if we 
manage to find some decent block space.

Cheers,
R.
