1800vitamins.org has a web site at 12.180.219.234 which looks like they would sell me vitamins should I or my dog need any.
Routeviews tells me that IP is in AS19111, routed via AS7018. AS7018 is AT&T which isn't surprising for a 12/8 address, but ARIN says AS19111 doesn't exist. Huh?
John you have no idea how many folks are using how many bogon ASNs as we speak. Nobody does. Even the guy who is doing weekly routing table reports isn't listing them all, I think, even after I talked to him and convinced him to list more things as bogon announcements than he formerly was listing. (I think his bogin lists are still not nearly complete, e.g. if one takes into account bogon ASN announcments.) Go to bgp.he.net and type in any number from 65000 upwards and look at all of the effing route announcements! These are all invalid/reserved AS numbers which *nobody* should be announcing routes for, at least not into the global routing table. And yet the Internet is absolutely awash in this garbage. Try to think of a word that is the absolute antonym of "hygiene" and that's the global routing table. This stuff would be funny if only it wasn't so sick and pathetic. Even if we forget about all of the morons who are -using- these invalid ASNs for actually routing bits to their IPs, you have to ask yourself: Who are all of the morons who are -peering- with these invalid ASNs? Regards, rfg P.S. Remember, out of all of the networking engineers in the entire world, by definition, half of them are of below average intelligence.
