It wasn't clear to me when I read the spec if these addresses are reserved globally for private networks or if DNSs connected to the internet always need an assigned IP address. > > TIA, > Bruce First you probably want to review RFC 1918, I believe that superseded RFC 1597 sometime ago. The address specified in those RFCs can be used by anyone on a private network. You need to select a subnet from the private address space for your network. Most home users end up using something in the 192.168.xxx range. A 24 bit subnet should be more that sufficient for a home LAN. (24 bit means you use a subnet mask of 255.255.255.0) You will need a device that with NAT your private address space to the public address assigned by your ISP. I always recommend one of the many inexpensive hardware firewalls such as Netgear or Linksys puts out. They are cheap and easy to setup. For a home LAN I would recommend you utilize /etc/host files to manage your addresses instead of a DNS. Just configure your /etc/resolv.conf files to point to your ISPs DNS servers. Maintaining a handful of systems using host files is fairly easy. Once you get that setup and working get the O'Riley book on DNS and read up on how to configure it. -- Scot L.
