[clug] Two networks, separate DNS: Fake Root?

[Jeff]

If it's just the one box (your host) you could edit /etc/hosts. 
Alternatively, if you want other machines on you local network to be 
able to find these hosts you may need to add authorative entries in the 
local dns server for the .lan zone. I'm guessing that you neither need 
or want different dns views, ie having the same name resolve to 
different IP address based on your source address. Unfortunately, I'm 
not familar with dnsmasq, but from a quick scan of the man page I'm 
guessing you can either add the hosts to /etc/hosts or create a another 
hosts file and use the *-H, --addn-hosts=<file>* option if you wish to 
keep the file separate for sys admining reasons.
