Whois Privacy is an important topic here at DomainTools. After all, a primary use of our Whois History product is to get behind Whois Privacy if possible. Just this week Brian Krebs wrote an interesting blog post that does a good job of showing the power of DomainTools’ Whois History.
Whois is also a prevailing topic seemingly every year at ICANN Conferences, and no debate about Whois data is complete without also discussing the benefits and costs of allowing domain owners to utilize Whois proxy services in order to shield their domain ownership from the public eye.
With the recent celebrity of Nate Silver, data is now in vogue more than ever. Data, assuming it is accurate, is fact not opinion. Data helps inform qualitative conversations, can lend momentum to important decisioning processes, and can uncover unknown information in unique ways. Take the first list in this article, below: That 94% number shocked me so I pulled up the Above.com homepage and sure enough, every domain at Above.com gets free privacy protection. Never knew that! So in the spirit of featuring more of our DomainTools data on this blog, we offer some insights below on the proliferation of whois privacy at the registrar and TLD levels.
It must be noted upfront that, due to the imperfect nature of both Whois data and privacy identifiers, no data set in this arena can be 100% accurate. Specifically we identify these caveats with the data:

* Nearly all the ‘private’ domains in .CN are associated with one registrar and privacy provider, and there are indications of underlying domain tasting on .CN as well. Absent this registrar, privacy on .CN is virtually nil.
We’re putting this new data to work at DomainTools as well. Our Whois History product uses color scheming to let users more easily identify privacy records in the reams of historical Whois records we have on file. The work our R&D team has done to update our privacy detection is going into production shortly, making related tools all that more accurate. Look for a redesign of our Whois History product coming soon!
