Some DNS recursive resolvers have longer-than-desired round-trip
times to the closest DNS root server. Some DNS recursive resolver
operators want to prevent snooping of requests sent to DNS root
servers by third parties. Such resolvers can greatly decrease the
round-trip time and prevent observation of requests by running a copy
of the full root zone on a loopback address (such as 127.0.0.1).
This document shows how to start and maintain such a copy of the root
zone that does not pose a threat to other users of the DNS, at the
cost of adding some operational fragility for the operator.
This document is a product of the Domain Name System Operations Working Group of the IETF.
