Re: Unified table of AS names?

Quick corrections to my email - 
 1. The problem with "UNSPECIFIED" is with RIPE (not ARIN) database
 2. when instaling ripe whois client, I'd recommend version "3.1" and not 
    the latest "3.1.1v.."

will give you nice one-line entry for each AS with its number, name and 
description (don't forget to install ripe whois v3 client and change some 
paths in script for it to work on your system)

There is however as you noted a problem with ARIN database as in many 
places for old AS numbers as-name is "UNSPECIFIED" - for all new AS this 
is required so its not as much of a problem. The script above deals with 
that by assigning pseudo-name "ASnumber" for all unspecified names.

And unlike geektools, completewhois will do recursive lookup for as in 
proper database (i.e. "whois -h completewhois.com as3320" in below case) 
but it just outputs all the data as is and I think for what you wanted, 
the pataroo script would work best.

I'm looking for a unified table of AS names or a tool that could be used
to generate such a table.

The table at ftp://ftp.arin.net/info/asn.txt only provides ARIN registered
AS names, using dig NNNN.rdi.int txt only provides ARIN registered AS
names as well, using the geektools whois proxy produces things like:

Which while you could write a hacked up script that scans for the first
description line after finding an aut-num line that was an exact match,
leave you wondering questions like is the as-name field unused in the RIPE
database (unlike the ARIN database)?

I figure there are several people out that that all must have solved this
problem independently, perhaps one of them would share?  :) :) :)
