Title: Only lookup the hostname once

This is a sample implementation that caches the lookup.

I'm not sure how to handle multiple IP addresses, so I've left it to pick the first one that's returned.

Maybe an extra switch that tells it "round-robin between multiple IP addresses if available" could be good?
