[Techtalk] DNS and IP masquerading

[Arashi]

I've been looking over a IPtables firewall script (kindly supplied by
Conor - thanks) and noticed that it includes DNS addresses.  ATM all
I know about DNS is that it maps machine names to IP addresses.  Do I
need
a DNS server for my situation (2 computers on a home network sharing
a dial-up internet connection)?


cheers
