Designing IP Addressing schemes and configuring IP Addressing is a common activity undertaken by network engineers. Consider an ISP is granted a block of addresses starting with 126.96.36.199/16. The ISP needs to distribute these blocks to 2500 customers as follows:
a. The first group has 180 medium-size businesses; each needs approximately 128 addresses.
b. The second group has 500 small-size businesses; each needs approximately 16 addresses.
c. The third group has 1800 households; each needs 4 addresses
Design the sub blocks and give the slash notation for each sub block. Find out how many addresses are still available after these allocations.
Consider the diagram below. Which of the two central routers (R1 and R2) is more critical for network operations and why?
