I don't understand what you mean by "leak" to the outside world. The
192.168.x.x range isn't gonna go anywhere, and besides, a host file
will do nicely for the local network.
A perfect example is my configuration here at home (my office is a SOHO
configuration).
The local network is config'd as 10.0.0.0 with a Cisco 762 ISDN router
working as 10.0.0.1 on the LAN side interface. The WAN side interface
is a PPP setup and the router does network address translation for the
entire network. The DNS domain doesn't exist (moongroup.org which is
one off from my real domain moongroup.com) so far as the net is
concerned.
On this network I've got two Linux boxen (RH5.0). One of them is a
"server", only because of the daemons it's running (sendmail, bind, smbd
etc.) and the other is a "workstation" because of the daemons it's "not"
running. I've also got an NT 4.0 box installed as a PDC and 4 Windoze
95 clients. 10.0.0.6 is running bind fully configured and all the
network hosts look to it for DNS. The Linux workstation is config'd for
cacheing bind only (I only did that to speed things up a bit and it
sped them up a lot!).
The only way you'd get any "leak" to the outside world is if you had a
fully routable network and the external DNS hosts had you in their host
tables. Other than that it ain't happnin'!
