We will be using an internal
private range. We will take
a private class A -10.0.0.0 and subnet it down to allow for 4000+
networks and 4000+ hosts. The
first 1000 subnets will be reserved for the district to assign to all
routers or to any other district devices. Then each school will receive 2 subnets for their use.
One will be dedicated to use on the student network and the other
for admin and teachers. This
will allow for each school to have a maximum of 4094 hosts available for
student use and 4094 hosts available for admin/teacher use.
Below is a table
illustrating the IP Addressing breakdown.
