The topology in Figure Q2(b) has network address of 25.0.0.0/8 and requires 1200 subnets.

Figure Q2(b)

(i)Determine the minimum number of subnet bits to borrow to meet the requirement. Show your working.

(ii)Give the resultant subnet mask based on your answer to Q2(b)(i). Show your working.

(iii)Based on your answer to Q2(b)(i), compute the following:

•The subnet address for subnet 99
•The range of host addresses for subnet 99
•The IPv4 address to be assigned to the PCs and interface of the router for subnet 99

Show your working.
