= IP range search
One promising way to find more of those would be with <IP> searches, since it was stated in the <Reuters article> that the <CIA> made the terrible mistake of using several contiguous IP blocks for those website. What a phenomenal <OPSEC> failure!!!
The easiest way would be if <Wayback Machine> itself had an IP search function, but we couldn't find one: <Search Wayback Machine by IP>.
https://viewdns.info was the first easily accessible website that <Ciro Santilli> could find that contained such information.
Our current results indicate that the typical IP range is about 30 IPs wide.
E.g. searching: https://viewdns.info/iphistory[] and considering only hits from 2011 or earlier we obtain:

Neither of these seem to be in the same ranges, the only common nearby hit amongst these ranges is the exact `68.178.232.100`, and doing reverse IP search at https://viewdns.info/reverseip/?host=68.178.232.100&t=1 states that it has 2.5 million hostnames associated to it, so it must be some kind of https://en.wikipedia.org/wiki/Shared_web_hosting_service[Shared web hosting service], see also: https://superuser.com/questions/577070/is-it-possible-for-many-domain-names-to-share-one-ip-address[], which makes search hard.
Ciro then tried some of the other IPs, and soon hit gold.
Initially, Ciro started by doing manual queries to viewdns.info/reversip until his IP was blocked. Then he created an account and used his 250 free queries with the following helper script: \a[cia-2010-covert-communication-websites/viewdns-info.sh]. The output of that script can be seen at: https://github.com/cirosantilli/media/blob/master/cia-2010-covert-communication-websites/viewdns-info.sh[].
Ciro then found <2013 DNS Census> which contained data highly disjoint form the viewdns-info one!
Summaries of the IP range exploration done so far follows, combined data from all databases above.
