Correct answer: the /18, and then some.

Oh, how you wished you hadn't posted this to the list (and Cc:'d
wholesalebandwidth.com on it), but chosen reply-to-poster :)

Random example from this block appearing in my rejects:
http://www.openrbl.org/lookup?i=69.6.4.153 or: "I see red!"

Extended answer directly from my auto-complaint override map:

 'as:26956' => 'as:17054,isp:cogent', # netfreeinc.com/wholesalebandwidth.com - rogue AS
 'as:11938' => 'abuse@yipes.com,isp:verio', # wholesalebandwidth.com - rogue AS
 'as:17054' => 'abuse@e-xpedient.com,isp:genuity,abuse@yipes.com,isp:gblx', # e-xpedient.com - rogue AS?

Anything announced out of 26956 and 11938 goes straight to the sendmail
access file here, and given the various pointers from OTHER rogues back
to 17054, e-xpedient.com routes will be there RSN, too.


And if you thought /18 is a big block in spammer-hand, go check out various
DNSBLs for listings and the history of AS's announcing portions of:

142.105.0.0/16
162.73.0.0/16
160.122.0.0/16
157.156.0.0/16
138.121.0.0/16
160.116.0.0/16
144.176.0.0/16
146.100.0.0/16
