Subnetting - Assume an organization has a pool of addresses defined by 223.1.17.0/24, and the organization wants to define three subnets: subnet 1, subnet 2 and subnet 3 from the pool that meet the following requirements: Requirement 1 - all the interfaces in each of these subnets have an IP address that starts with 223.1.17.0/24
Requirement 2 - subnet 1, subnet 2 and subnet 3 support at least 60, 90 and 12 interfaces respectively.
Requirement 3 - the subnets do not overlap, i. e. an interface belongs to only one subnet
Requirement 4 – bits 25 and 26 of the subnet 1 prefix should be zero (The first bit is numbered as bit 1)
In the following, for simplicity, you may assume that a host part of n bits can support 2^n (2 to the power of n) interfaces. (In reality, there are some special reserved addresses that cannot be used for an interface.)
Find three network prefixes for subnet 1, subnet 2 and subnet 3 subnet 3 (one prefix for each of the subnets) that satisfy the requirements 1, 2, 3 and 4, with the smallest possible host parts. Note that some addresses in the original pool may be unallocated to any of the three subnets, and there is no unique solution that satisfies the constraints, you just need to provide one.
List the network prefixes of subnet 1, subnet 2 and subnet 3 (in that order) in the a. b.c. d/x form, where the prefixes are separated by a comma. A hypothetical example of network prefixes in that format is:
8.0.0.0/9, 24.3.0.0/16, 3.128.0.0/10
Where 8.0.0.0/9, 24.3.0.0/16, 3.128.0.0/10 are the prefixes in the a. b.c. d/x form of subnet 1, subnet 2 and subnet3 respectively.
