Re: who gets a /32 [Re: IPV6 renumbering painless?]
Paul Vixie wrote:
Here is a possible multi level solution for end sites and non /32 qualifiers:
- Sites that dual-home use alternate path encoding with PA /48's
- Sites that tirpple home do the same but get PA /40's to make up for the loss of site subnet
bits in tripple mode.
- Sites that multihome 4 ways or more get a PI /40
- Large sites with more than X devices get a PI /40 if at least (dual|tripple)homed
to avoid massive renumbering/provider lock-in.
This would set the bar high enough to limit routing table growth while allocating
PI space to those who need it the most.
