Reiterating nonsense does not change its character. That particular reiteration of Mr. Hall's thesis contains two valid statements that are either independent of his original thesis or that contradict it. It is not clear what Mr. Hall intends by his first sentence. As far as I can tell, Mr. Hall supports the notion that dividing one of the current large TLDs into N smaller, approximately equal sized, each quite large TLDs would not cause an approximately linear increase of N times as many hits on the roots. An equivalent statement is that combining N of the current large TLDs into a single TLD would not reduce the number of queries for the roots by a factor of N. Mr. Hall's thesis has been disproven in several recent comments. I think one of those comments came from Mr. Hall himself. That comment was when he noted that his server's cache had entries for both .com and .edu. Those two entries required his server to query the roots twice. If .com and .edu were merged, then Mr. Hall's own servers would have made half as many queries of the roots. Vernon Schryver vjs@rhyolite.com
