Consider a subnet with prefix 128.119.40.128/26. Give an example of one IP address (of form xxx. xxx. xxx. xxx) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 128.119.40.64/26. Suppose it wants to create four subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form a. b.c. d/x) for the four subnets

Check the explanation

Explanation:

The step by step solution to the answer above can be seen below, kindly indicate any barrier through the comment box.

IP address range: 128.119.40.128 ‐ 128.119.40.191

Note: 128.119.40.128(last 8 bits: 10000000, reserved address), 128.119.40.191(last 8 bits: 10111111, reserved address, broadcast)

Four subnets:

   128.119.40.64/28

   128.119.40.80/28

   128.119.40.96/28

   128.119.40.112/28

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
