This isn't how the DNS works. See Sean Donelan's comments on the data CAIDA has collected. It would improve performance for the first querier at a site (or some level of aggregation, depends on the caching infrastructure, of course) every 8 days or so. > Definitely seems interesting to me, even though issues with keeping data > up-to-date are of critical importance here. There is nothing stopping any ISP from doing what Randy suggested today, particularly given several of the root servers allow zone transfer. Similarly, there is nothing stopping any ISP from advertising addresses for (say) Google and making sure only government approved pages are returned. To borrow a term from Mr. Bush, it would be "prudent" to wait for DNSSEC signing of the root before going down the "pretend to be a root server" road.
