3.Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.1.17/24. Also suppose that Subnet 1 is required to support at least 60 interfaces, Subnet 2 is to support at least 90 interfaces, and Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints

ANS：

223.1.17.0/26

223.1.17.128/25

223.1.17.192/28

I'm not sure if my answer is correct, could you give me a detailed answer,I'm not sure how to compute the 223.1.17.x.

this question is from:

Three different subnets named Subnet 1, Subnet 2 and Subnet 3 are interconnected in a network and the interfaces related to these subnets require a prefix 223.1.17/24. Subnet 1 that supports minimum of 60 interfaces requires the network address 223.1.17.0/26. The network address required by the Subnet 2 that supports minimum of 90 interfaces is 223.1.17.128/25. Subnet 3 which supports at least 12 interfaces requires the network address 223.1.17.192/28. | bartleby
