Re: Email peering (Was: Economics of SPAM [Was: Micorsoft's Sender IDAuthentication......?]

Of course, there's already one application-level messaging protocol that relies extensively on arranged peerings: Usenet. Usenet doesn't rely on a *full* N-way mesh of arranged peerings, it relies instead on a core of fairly well interconnected "backbone" or "core" news sites who've agreed to do feeds with each other, as well as to feed downstream "leaf nodes" (either on a for-fee commercial basis, or gratis as part of a regional consortia or whatever). To receive traffic or originate traffic, a leaf node doesn't need to peer with every other news server, it just needs to do feeds with a couple of upstream core sites to insure that it has reasonable coverage and redundancy. Spam isn't much of a problem on Usenet anymore because peers who tend to have spam issues tend to clean them up or get depeered or shunned... There's no reason why one couldn't build a comparable model for mail, with the SMTP speciality service provider offering "SMTP transit" to a base of trusted customers. This comparatively small number of SMTP speciality provider would then maintain good relations ("peerings") with the comparatively small number of major ISPs. Oh wait -- there are a variety of folks who are already specializing in doing that sort of thing -- it's just that most folks don't need to buy that sort of service (yet).

ARIN's new allocations from IANA
by Leslie Nobile 18 Jun '05

18 Jun '05

Hello- ARIN received the IPv4 address blocks 74.0.0.0 /8 and 75.0.0.0 /8 and 76.0.0.0 /8 from the IANA on June 17, 2005. In the near future, ARIN will begin making allocations from these new blocks. This will include allocations of /20 and shorter prefixes, according to ARIN's minimum allocation policy. You may wish to adjust any filters you have in place accordingly. For informational purposes, a list of ARIN's currently administered IP blocks can be found under "CIDR Blocks" at: http://www.arin.net/statistics/index.html Regards, Leslie Nobile Director, Registration Services American Registry for Internet Numbers (ARIN)

Well, I just looked up addresses in a few of my blocks, and geobytes either had wrong info or no info. If you're the ISP, then your answer to your customers is "the web site you are going to is using an unreliable method to attempt to determine locality from IP address." Then point them at the web site's contact form and suggest they complain to the web site owner. As you've already noted, ARIN got the info correct. I suspect there are multiple vendors attempting to provide IP address to GPS address services. I doubt any of them will be 100% reliable, but clearly there is an interest in such services.
