I don't think this is correct. ntpd *IS* a time server and the IP address is the address of the machine you run it on. On my private network, I have a FBSD box on 192.168.20.4. I have a Win2K machine on 192.168.20.3. I have a ntp client program called "Automochron" that runs on the Win2K machine. In the client, I have the time server listed as 192.168.20.4 (the FBSD machine). The Win2K client gets time updates. I don't remember doing anything special with ntpd to set this up. I just used the standard xntpd that is bundled with the basic OS, put time server entries in ntp.conf, and ran the daemon. Please, anyone correct me if I'm missing something.
