How many usable host addresses are available in a /29 subnet?

Explanation:
Subnet sizes determine how many host addresses you can use. In a /29, there are 3 host bits, so there are 2^3 = 8 total addresses in the subnet. The network address (all host bits zero) and the broadcast address (all host bits one) can’t be assigned to hosts. Subtracting those two leaves 6 usable addresses. For example, in a 192.168.1.0/29 block, usable hosts are 192.168.1.1 through 192.168.1.6, while 192.168.1.0 is the network and 192.168.1.7 is the broadcast. So, the number of usable host addresses is 6.
