9-3. A firm is assigned the network part 128.171. It selects an 8-bit subnet part. a) Write the bits for the four octets of the IP address of the first host on the first subnet. b) Convert this answer to dotted decimal notation. (If you have forgotten how to do this, it was covered in Chapter 1.) c) Write the bits for the second host on the third subnet. (In binary, 2 is 10, and 3 is 11.) d) Convert this into dotted decimal notation. e) Write the bits for the last host on the third subnet. f) Convert this answer into dotted decimal notation. Can you tell the subnet a host is on just by looking at the dotted decimal notation representation?
