SocialDNS was a novel naming infrastructure for locating information in the World Wide Web. As of 2014 it is no longer operational. It was an open network of Web servers that maintain and resolve domain names under a new URL scheme (go://).
Users could obtain names for free in new TLDs (.blog, .name, .socialdns, …) and organizations could manage their own TLDs (.ibm, .sun, .barcelona). Everyone could test go:// addresses in www.socialdns.net. Users and organizations were invited to enter this public network.
There is a Historic Timeline dedicated to the Social DNS project.
