Which of the following is a valid host address range for subnet 15.242.55.62/27?

To determine the valid host address range for the subnet 15.242.55.62/27, it is important to first understand how subnetting works.

A /27 subnet means that the subnet mask has 27 bits set to 1. In decimal, this translates to a subnet mask of 255.255.255.224. This mask results in 32 addresses in total (2^5 = 32). However, two addresses are reserved: one for the network address and one for the broadcast address. Therefore, in a /27 subnet, there are 30 valid host addresses.

To calculate the network and broadcast address:

1. The subnet includes addresses starting from 15.242.55.32 (which is the network address) and goes up to 15.242.55.63 (the broadcast address).

2. The valid host addresses will be from 15.242.55.33 to 15.242.55.62.

Given this, the only valid range of host addresses that fits within the subnet defined by 15.242.55.62/27 is from 15.242.55.33 to 15.242.55.62. This range allows for the use of
