There is no such thing as "Internet routers" there are my routers, your routers, and that guy over there's routers. Even if you get your ISP to route it for you - that does not guarantee that any other network anywhere else on the internet will accept the route. Getting your ISP to accept your prefix is arguably, only a small part of being reachable/routable. --Heather -----Original Message----- From: Naslund, Steve [mailto:SNaslund@medline.com] Sent: Thursday, September 20, 2012 10:56 AM To: nanog@nanog.org Subject: RE: RIRs give out unique addresses (Was: something has a /8! ...) I suppose that ARIN would say that they do not guarantee routability because they do not have operational control of Internet routers. However, Wouldn't you say that there is a very real expectation that when you request address space through ARIN or RIPE that it would be routable? I would think that what ARIN and RIPE are really saying is that they issue unique addresses and you need to get your service provider to route them. FWIW, the discussion of the military having addresses pulled back is pretty much a non-starter unless they want to give them back. When the management of IP address space was moved from the US DoD, there were memorandums of understanding that the military controlled their assigned address space and nothing would change that. I know this for a fact because I was around this discussion in the US Air Force.

It's very clear in the ARIN region as well. From the ARIN Number Resource Policy Manual (NRPM), <https://www.arin.net/policy/nrpm.html#four11> -
"4.1. General Principles 4.1.1. Routability Provider independent (portable) addresses issued directly from ARIN or other Regional Registries are not guaranteed to be globally routable."
While close, that is not the same.
The RIPE variant solely guarantees uniqueness of the addresses.
The ARIN variant states "we don't guarantee that you can route it everywhere", which is on top of the uniqueness portion.
Agreed - I called it out because ARIN, like RIPE, does not assert that the address blocks issued are "publicly routable address space" (i.e. which was Tim Franklin's original statement, but he did not have on hand the comparable ARIN reference for that point.) FYI, /John
