2. Not all parts of all questions are assigned. Review the question assignment above to make sure you answer what is required for each question.
3. Answers should…show more content… Subnet masking select network and subnet part of IP address. Host part:This part of the IP address correspond to particular host on the subnet. Each host is assigned a unique address on the network. For each host on the network, their network part will be same, but host part will be different.
b. Length of IP address: As the IP address is the combination of the three parts, so they have separated length. Each part of the IP address is not of fixed length, only they can’t be less than 8 bit. In Normal IP addressing from the text book figure 8-2, the length of each parts is defined as: Network part: 16 bits. Subnet part: 8 bits. Host part: 8 bits.
c. As the IP address is the combination of the three parts, so the total length can be calculated with the length addition of three parts. The total length of the IP address is 32 bits. From the figure 8-2, it can be seen as: Total length of IP address=Network part length + Subnet part length + Host part length
d. IP address 10.11.13.13 is the private address and in Private IP address, there is no way to define the length of the network part without having subnet mask. The total length of this address is 32 bit but it is impossible to calculate the length of network part in this type of address.

a. A mask has 32-bits with initial bits as 1 followed by zeros. An example of mask is 255.255.0.0 in this the binary representation of initial
