Network Protocols

A network protocol is a set of rules that govern how data is exchanged between the devices in a network. Network protocols enable communication between devices that are located in different parts of the world. Consequently, they are critical in today's digital communications.

Question

An ISP has purchased address
domain 200.100.0.0/20. If this ISP
has 5 customers who want 120,
350, 68, 623 and 128 addresses,
respectively. Answer the following
qustions.
- Specify the address space required
for each customer. Address space
means determining the network mask
along with determining the start and
end address of each network.
- After assigning the address to these
customers, how many free addresses
are left to the ISP?
Tip: To determine the range of
customer addresses, start with
customers who want more addresses
and then allocate address space to
- customers with fewer addresses.
