Whats the difference between recursive and authoritative queries?
Clients on our network issue recursive queries to our caching nameservers to look up names of hosts on-and-off campus. The caching servers can start from the root servers and work their way down the nameserver chain, talking to the authoritative servers for domains along the way. Note that we’re now configuring our authoritative servers to bounce recursive queries except from netdev-net. This is to reduce load and prevent users from incorrectly using the authoritative servers as caching servers. In doing so, we can move the servers easier down the road, as the only reference is via NS records that we can control.
