Study Notes
Subnet Masks
- The primary purpose of a subnet mask is to determine the scope of a subnet, and to identify which part of an IP address represents the network ID and which part represents the host ID.
Default Subnet Masks
- The default subnet mask for a Class B IPv4 address is 255.255.0.0.
Subnet Masks and Hosts
- The subnet mask that would allow for the largest number of hosts on a network is 255.255.255.0, as it uses the least number of bits to define the network ID, leaving the most bits available for host IDs.
