Suppose you are an ISP that owns a / 22 IPv4 address block. Can you accommodate requests from six customers who need addresses f
lisabon 2012 [21]

Answer:

It is not possible.

Explanation:

In this example, we need to accommodate 473 computers for six clients that are 473 IP addresses.

For this request just we have /22 IPv4 address blocks, this mean

22 red bits 11111111111111111111110000000000 <--- 10 host bits

We must increase red bits to 25, we need these 3 bits to create 6 sub red, in this case, 2^3 = 8 sub red.

Why did we ask 3 bits? Because if we ask only 2, 2^2 = 4, and we need 6 sub red.

25 red bits 11111111111111111111111110000000 7 host bits

In this case, we need more than 260 computers, but just we have 7 bits, this means.

2^7 = 128 and just one customer needs 260, for that is impossible.

P16 Consider the following network. ISP B provides national backbone service to regional ISP A. ISP C provides national backbone
Art [367]

Solution :

Considering the following data :

$\text{ISP B}$ provides the national backbone to the regional $\text{ISP A}$.

$\text{ISP C}$ provides the national backbone to the regional $\text{ISP D}$.

Each of the ISP consists of one autonomous systems (AS).

$\text{ISP B}$ would like to hand over the traffic of C through the $\text{West}$ Coast.

The $\text{ISP C}$ would like to receive traffic from B's peering point via East Coast.

One way for $C$ to force $B$ to hand over all of $B$’s traffic to $D$ on the east coast is for $C$ to  only advertise its route to $D$ via its east coast peering point with $C$.
