Why would ARIN specifically provide such a list? ARIN is not responsible for the unallocated space, and there is more in the world than just ARIN. There are liability issues with that, not to mention the fact that it is more an IANA function (if for the sake of argument someone would implement the list).
The problem here is that ARIN (and the other registries) are the ones who can contact the users. When these things change all ISP's need to be notified. As much as many people on this list think that every ISP in the world reads Nanog it just isn't so. Who has a list of ISP's? Well, depending on your view of things I think a good argument can be made that it's either the list of everyone with an ASN (my preference, since those are the people who's route filtering matters), or everyone with IPv4 space allocated to them. The only entity with either of those lists is the registries, ARIN, RIPE, APNIC and soforth. If the offical notice needs to come from IANA that's fine, but it needs to go out to the list of members of the registries. IMHO it is there job to make sure IANA has a way to send those sorts of messages. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org
