consider that, to do the work described as "forwarding" in many of

it must perform a query with the rd bit set].

cache to improve DNS resolution times for clients. However, it actually
does none of the recursive querying itself. Instead, it forwards all
requests to an outside resolving server and then caches the results to
use for later queries."
What am I missing?
Justin Ellingwood, who wrote the DigitalOcean piece, is a very
experienced documenter. From his rather impressive resume, I'd be
inclined to trust what he posts.
This is the difference between asking a question (formulating a query
potentially with the "want recursion" bit set) and then doing the work of
chasing down all the different stake-holders necessary to answer the
question (performing the recursive query)
VS handing the query off to a 3'rd party and letting them do the dirty
work (forwarding)
