Refer to the example that was discussed in the IP Addressing

Refer to the example that was discussed in the IP Addressing lecture where a large number of consecutive IP addresses are available from 198.16.0.0. Suppose that four companies A, B, C and D respectively require 4000, 2000, 4000 and 8000 addresses (requests arrive in that order). In the lecture, we covered the first three companies A, B, and C, continue the example by giving:

1. the first IP address assigned for company D,

2. the last IP address assigned for company D,

3. the allocated block for company D, using the notation w.x.y.z/s .

Show your work.

Solution

First address assigned for comapny D is 192.16.0.1/19

Last address assigned for company D is 192.16.31.254/19

Broadcast address is 192.16.31.255/19

Allocated block = 192.16.0.1 to 192.16.31.254

Subnet mask = 255.255.224.0
