How many hosts are addressable on a network that has a mask of 255.255.255.248?
- 2
- 6
- 8
- 14
- 16
- 254
Explanation: The subnet mask of 255.255.255.248 is the same as /29. This means the network portion of the address is 29 of the 32 bits in the address. Only 3 bits remain for host bits. 2^3 = 8, but one of these addresses has to be used for the network number and one address must be used as the broadcast address to reach all of the hosts on this network. That leaves only 6 usable IP addresses that can be assigned to hosts in this network. Don’t forget that the default gateway must be one of these devices if this network is to communicate with other networks.
