Subject: [Arin-whoisrws] identify isp owner based on ip address
Message-ID: <AANLkTimZ=G8eP4L98FeQ36M1OCJLG-nNy74tDC+AAab0@mail.gmail.com>

I'd like to get a list of every network out there so I can see what isp is
used for a specific ip address.  I have 50,000+ addresses to evaluate based
on traceroute and whois data.

Is there a list of all ip address ranges and the owners of those blocks?

I see many whois responses show a section like this:

AT&T WorldNet Services ATT (NET-12-0-0-0-1) 12.0.0.0 - 12.255.255.255

Is there a master list containing the entire listing of all
whois.arin.netrecords?

Thanks.

Without seeing your queries, I don't understand why this might be a concern.  If
it's regarding more specifics, there are certainly more specific assignments
within 12.0.0.0/8: http://whois.arin.net/rest/cidr/12.0.0.0/8/more.  If you're
not seeing anything more specific, the block/address in question may not be
assigned or may be in use by the ISP itself.  Note that I am not a network
operator -- caveat lector.

I just want to second Steve's comment. It sounds like what you are looking for is the Bulk Whois data set.
