a) You didn't actually calculate the cost of the recursive solution, you simply pulled a large number of servers needed out of thin air. b) You didn't say why would need any fewer authoritative servers to get the same benefit. The amount of benefit of either solution is being debated. However, I am not sure you can show any greater benefit to an end user of getting a validated answer for a root query with the AA bit set on vs. off. > if you consider the number of operators involved, their skill and motivation > levels, and the number of affected end users -- in each case -- you should be > able to reason your way to the same conclusion. I am not. (But I won't claim that you "should be able to reason" your way to the opposite conclusion.) You postulated a larger number of unskilled operators without any justification for the recursive servers. If the goal is to get the correct answers for root queries closer to more users, both proposals do that. --Paul Hoffman _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
