   My network is all hidden behind the ADSL modem running NAT and my
firewall running masquerading, with private addresses. I have my own BIND9
DNS server that covers my network which serves all the local boxes, and acts
as relay for all DNS searches for external addresses, with DNS provided by
my ISP. The real addresses for my local boxes can be glimpsed in parts of my
header, but are not accessible from outside.
