Subneting????

by shanghai sam . Updated 24 years, 5 months ago

Please examin the following imaginary senario;
Company X has 2 routers,X1 and X2.
Router X1 is located at the Admin Offices and holds the admin LAN.
Router X2 is located at the Warehouse and holds the designers LAN.
Router X1 and X2 are connected through a serial cable.

The NT IP address is 150.8.0.0 subnet mask 255.255.248.0 (5 bits borrowed from host field)
This allows for 32 Subnets/2048 hosts.

Let’s say
150.8.0.1 to 150.8.7.254 for E0 Router X1 (Admin LAN)
150.8.8.1 to 150.8.15.254 for E0 router X2 (Designers LAN)

OK
But this is what I don’t understand;
to the router’s serial ports I would assign
150.8.16.1 to S0 on router X1. and
150.8.16.2 to S1 on router X2. (connected via Serial)

NOW my question is; what happens to the other 2044 available addresses in subnet 3?
I can’t assign them to any other interface because they are different networks.
Does that means that all does addresses get wasted or is there other way to do it without wasting all does addresses?
Please explain!
Thanks.
