   12: # The following two options make you a better netizen, since they
   13: # tell dnsmasq to filter out queries which the public DNS cannot
   14: # answer, and which load the servers (especially the root servers)
   15: # unnecessarily. If you have a dial-on-demand link they also stop
   16: # these requests from bringing up the link unnecessarily.

   27: # so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk.

   76: # You can control how dnsmasq talks to a server: this forces

   78: # server=10.1.2.3@eth1
   79: 
   80: # and this sets the source (ie local) address used to talk to
   81: # 10.1.2.3 to 192.168.1.1 port 55 (there must be a interface with that
