On the topic of IP4 exhaustion: 1/8, 2/8 and 5/8 have all been assigned in the last 3 months yet I don't see them being allocated out to customers (users) yet.
Is this perhaps a bit of hoarding in advance of the complete depletion of /8's?
Doubt it. 1/8 is still being evaluated to determine just how usable portions of it are, thanks to silly people of the world that decided 1.1.1.x and the like were 1918 space.
As for the others, the RIR requests it when they are running low, but certainly not exhausted, and as slow as people are to update their bogon filters, it sounds like general good practice not to assign out of a new /8 until pre-existing resources are exhausted.
Was looking for the "allocated" file on the ARIN website, but can't remember where it is. They used to have a file with one line per allocation that started like this "arin|US|ipv4". Is that still public somewhere?
If you are looking for what blocks have been allocated to ARIN by IANA, the file is maintained on the IANA site: http://www.iana.org/assignments/ipv4-address-space/ If you're referring to the IP space ARIN has issued out, I don't know if there is a single authoritative text list (at least I couldn't find one quickly). There is a mailing list maintained by ARIN that tracks daily issued blocks, but it appears to have archives going back only to late 2k8: http://lists.arin.net/mailman/listinfo/arin-issued Steve
