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

The question seems to be incomplete or incorrectly formatted. In order to determine the broadcast address, we need to know the subnet mask or CIDR notation. However, based on the range provided (81-86), it seems like this could be a small subnet with a /29 CIDR notation.

Here's a step-by-step guide on how to find the broadcast address:

1. Identify the network address: This is usually the first IP address in your subnet range. In this case, it would be 81.

2. Identify the subnet mask or CIDR notation: As mentioned, this information seems to be missing from your question. But if we assume a /29 CIDR, it means that the first 29 bits of the IP address are used for the network address and the remaining 3 bits are used for host addresses.

3. Calculate the number of hosts: The number of hosts in a subnet can be calculated using the formula 2^(32 - subnet mask) - 2. For a /29 CIDR, this would give us 6 hosts.

4. Identify the broadcast address: The broadcast address is usually the last IP address in your subnet range. In this case, if we assume
