1) Suppose an ISP owns the block of addresses of the form 204.0.0.0/k in CIDR notation, where k=X+Y+7. Suppose it wants to create four subnets from this block, with each subnet having the same number of IP addresses. What are the prefixes (in CIDR notation a.b.c.d/h) for the four subnets? Justify your answer.
X = 5 Y = 2
- Suppose the ISP in question 1 would like to change the partitioning of its block of addresses, e.g., subdividing the block into 8 subnets. Does this change need to be advertised to other networks? Explain your reasoning. Suppose the addresses in one of the subnets were used by a company, a client of the ISP.
What would happen to the companys IP addresses if it changes ISPs?
