Final answer:
A /29 subnet provides 6 usable host addresses, calculated by deducting the network and broadcast addresses from the total 8 addresses in the subnet.
Step-by-step explanation:
The number of usable host addresses in a /29 subnet is 6. In IP addressing, a /29 indicates a subnet mask of 255.255.255.248, which allows for 8 total IP addresses. However, 2 addresses are reserved: one for the network address and one for the broadcast address. Therefore, the number of usable IP addresses for hosts is 8 total addresses minus these 2 reserved addresses, resulting in 6 usable addresses.
