I understood the DHCP You could, but it would be up to the DHCP *server* to assign the client the same static IP each time, not up to the client.

The server assigns the IP address, the gateway address, and other needed information. The client figures out the routing, though. > As a related example, I have a static IP with a dialup account.

As long as the dialup server sends your machine the correct gateway and subnet mask, your machine properly figures out the routing from itself to the gateway. > The static IP is dynamically assigned in the dialup negotiation, and somehow > the routing is set up dynamically in the ISP's network. Right -- as I said above, though, it's assigned to you by the server. In some cases, you can configure it manually, and the dialup server will see that you've configured an IP and will try to use it. However, most ISP's don't work that way anymore, because someone could deliberately configure their machine with someone else's IP address, knocking that other person off the 'net. Nowadays, most likely, if you hard-code an IP address into your machine, and the server sees that, it'll just disconnect you. ********************************************************************** * Bryce Newall * Email: data@dreamhaven.net * * WWW: http://home.dreamhaven.net/~data * * "Insanity takes its toll.
