I have a client who has been assigned a /20 from ARIN.

They asked me to help them with their DNS.

The DNS for me is the easy part. except...

ARIN has told them that you use the DNS to set up the routing so that
the traffic for this /20 gets routed to the correct up-stream provider.

Is this correct? If so, where in DNS do you set up routing.
if it's not correct, what am I missing? I always thought DNS had 100%
nothing to do with routing on the 'net. Boy am I confused.
