Try not to think of static reservations as a rigid method of implementing DHCP, but rather a flexible way to implement static IP's. Static reservations are also quite reliable.

Agreed. Static reservations are a bit of a compromise with a fully dynamic configuration. > I wonder -- if I remove all my machines from the LAN for a month (so the > router forgets the configuration) and reconnect them in a different order > than I did originally, will the IP addresses still stay the same? Yes. If you are really using static reservations, the router will not "forget" them. It is often the client that keeps the address the same. When a DHCP client renews its address, it will first send a unicast to the previous DHCP server requesting a renewal or new lease of the same IP that it last had. > I thought > the way DHCP works is that when the router sees a machine it hasn't seen > before, it assigns it the lowest available IP number in the DHCP range. Most do this. (Assuming, of course, that no reservation exists for that MAC address, and the client did not request a different address) -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
