If the host range for a subnet is 81–86, what is the broadcast address?81868780

1. ### Break Down the Problem

To find the broadcast address for the given subnet, we start with understanding the host range. The host range provided is from 81 to 86. This gives us the following key points:

• The first usable address (host) is 81.
• The last usable address (host) is 86.

2. ### Relevant Concepts

In a subnet, the broadcast address is the highest address in the subnet, which is reserved for broadcasting messages to all hosts on the subnet. The broadcast address is always one less than the next subnet's network address.

3. ### Analysis and Detail

To calculate the broadcast address:

1. The first usable address is 81.
2. The last usable address is 86.
3. Broadcast address is the last address in the subnet. If the last usable address in the subnet is 86, the broadcast address would typically be 86, but since we want the address for broadcasting purposes, it will be equal to the next address after 86 in terms of the whole subnet.

Assuming the subnet mask allows for this range:

• The subnet could either be a /26 or another mask that accommodates these values specifically. However, based on the given range (81–86), we will assume a subnet mask that includes these addresses.

Since the broadcast address would be the network address plus the number of usable hosts, we can directly say:

• Broadcast address = 86 (last usable host) + 1 = 87.

4. ### Verify and Summarize

If the provided range is from 81 to 86, then the broadcast address logically follows at 87.

Final Answer

The broadcast address is 87.
