You could try just using the ping or host commands, they will also try to resolve the domain.

Also can you access the services by using IP:Port?

I have several grocery stores of different chains in my vicinity, in a 3km radius I could probably choose between 10+ locations (I just checked after posting: There are at least 18 grocery stores within that range and some options like farmer markets not listed). I only go to the closest ones (~500m) by foot, for most things further away I take my bike.
