Gary Warner wanted to find out and has now posted the Mother of all Lists of (almost) all Intercage domains
From Gary: “The domains listed … all came from the sites above, but it is not an entirely complete result. My tool would only allow 2,000 domains per IP, and there were two IPs that exceeded that limit.
184.108.40.206 had 3,978 domains listed, and 220.127.116.11 had more than 10,000 domains listed. Both of those result sets were truncated as a result.” (More explanation here).
At any rate, the list, sans those two IPs, is here (txt).
Nice work, Gary. A very useful list indeed.
