host vs dig

got a little network of 5 machines set up here at home (not connected to the internet).

if sitting on a machine I can ping and 'dig' any machine name I like (so long as I append for the dig command).

However if lets say 'dig +short' returns

and I then execute 'host' why does host come back with "timed out; no servers could be reached".

what's the deal here why can't I do reverse lookups?

'Timed out; no servers could be reached' is a message from your system regarding connecting to your DNS server. 'host' is trying to connect to your DNS server (specified in /etc/resolv.conf) and look for a DNS zone containing a '12' PTR record in which it's not finding because DNS is apparently broken on your system. You cannot perform reverse lookups with 'host' against /etc/hosts, because 'host' is meant to be a DNS tool.

I imagine that forward lookups are working fine via /etc/hosts (which is controlled via /etc/nsswitch.conf; 'hosts: files dns').
