I assume that the top "Google RN" link refers to "RealNames", which was a cross between AOL keywords and an alternate domain name system. It surprising to see that there, because canonical registries (i.e. Yahoo, RealNames) are kinda the antithesis of what Google was pioneering at the time (i.e. PageRank).
