Your IP address bitwise ANDed with the netmask yields the network. The network address bitwise ORed with the negated netmask yields the broadcast. The router's IP is the gateway. An example: IP: 192.168.0.34 (0xc0a80022) Mask: 255.255.255.240 (0xfffffff0) 0xc0a80022 & 0xfffffff0 = 0xc0a80020 (192.168.0.32) 0xc0a80020 | ~0x0f = 0xc0a8002f (192.168.0.47) You can do all these calculations with perl :) I'll elaborate if people care ... > Would anyone have example /etc/network/interfaces syntax for configuring the > automagic of DHCP?

Then maybe I can boot into one of Linux's graphical UI's ;) Dunno about this, though I've had great luck with Xfree86 4.x. I'm not a Mac guy though so perhaps Ethan can answer this one.
