Not really, unless I'm getting something wrong. :)
The resolver (gethostbyname(3) & friends) is a libc routine. So
you won't see /etc/hosts queries on the network and needn't see
them when tracing syscalls.
But yes, one could watch DNS queries with some libpcap mechanism
(tcpdump being the most famous of them). But then it might be
easier to talk the named on the server side into logging, see
"man named" for details if that's what you have running there.
Unless the LAN is somewhat bigger and you need the filtering
capabilities tcpdump provides you with.
