Fake DNS

[Scott <mecimojs @ clwoc1 . dnet . dupont . com>]

I have read several articles on DNS on the firewall. One suggestion is to 
return fake addresses for queries instead of returning UNKNOWN in which
cross-checks fail. In making special-format host names, do you need to
make one for each IP node ? Do you return real IP addresses ? What does the
PTR records look like ? Any help would be greatly appreciated or if you can
direct me to a ftp site for more information .
