I'm not an expert, but can/should you advertise ARIN IP space on APNIC or RIPE, etc ? You are talking about having recieved ip space from ARIN, tied to an ARIN AS.... I suppose it's probably more a matter of form than anything else though..... On Tuesday, December 22, 2009, Nathan Ward <nanog@daork.net> wrote:
The assumption that networks will filter /48s is not the whole story.
The RIRs giving out /48s do so from a single pool that only contains /48 assignments. The RIRs give out /32s from a pool containing /32 or shorter prefixes (ie /31, /30, etc. etc).
You will find that most networks filtering /48s allow them from the pool with only /48s in it.
The root DNS servers are in /48s.
If you can justify getting a /32, then I suggest you do so, but if not then don't worry, a /48 will work just fine. The networks that do filter you will pretty soon adapt I expect.
Insert routing table explosion religious war here, with snipes from people saying that we need a new routing system, etc. etc.
So with that in mind, do your concerns from your original post still make sense?
