On Linux (ignoring the router for the moment) you would have a linux server (192.168.0.1) handing out ip addresses (in some range e.g. 192.168.0.[10-100]) via DHCP. The DHCP server would point clients to itself (192.168.0.1) as the BIND nameserver. BIND (named) would be running as a caching BIND server handing out IP addresses it knows about and looking the rest up via a root BIND server. The trick is to get dhcpd to talk to named and update ip addresses as clients connect on the internal network. Then named knows all internal (192.168.0.x) addresses, and looks the rest up. Some routers can handle this, some can't. I had a LinkSys wireless hub that did the DHCP part, but didn't store the addresses for later lookup via local DNS. Right now I have a nice wireless/DSL/router box that does the DHCP/DNS correctly, no thought required. -- Carl Nygard <cjnygard@xxxxxxxx>
