Hi,

Just trying to get some clarity and direction regarding obtaining
address space/ASN for my client.

Is there a minimum address space (?) an entity would need to justify to
go directly to RIR (ARIN in this case) as opposed to the upstream
provider? Is /20 the minimum allocation? Can my client approach RIR and
request for a /23?

If my client do procure a /23 how do they make make sure that this
address space will be globally routable?

Multihome will also be part of their network implementation, can they
apply for an ASN number?
Yes, minimum assignment is /20 (and this is considered temporary, as the official minimum is /19) -- there used to be some experimental /24s, but I believe these are now gone. ARIN will only assign /20 or more -- larger prefixes must come from your upstream provider. Being multihomed means you will be required to get an AS number. Once you have your address block, you can fill out the request from ARIN.
