This is a question posted by Jeremy Zawodny. Just like to give a heads-up to ITU SPU Newsblog who gives an excellent explaination why Jeremy is not only wrong, but off the mark.
The question is interesting but wrong since the comparison between a search engine and a deterministic lookup service like the DNS is comparing apples and oranges even if they at first appear to provide an analagous service.
For those who is interested to explore further, you should read John Klensin’s RFC 3467 on DNS Roles.
