IP Addressing
Each of the four subnets can, in turn, support 64 members.
The example subnet used above yielded 4 subnets, but you can use a different mask to meet the specific requirements of your network.
Default Gateways
A default gateway is a network device, usually a router, that is responsible for routing data packets out of the local network segment.
The address of the gateway is entered into the devices on the local network, providing them with a location to send data that is destined for another segment.

MAC Addresses
A MAC address is a physical hardware address that gets assigned to the inter- face of a networking device. This address is typically created and burned into a device’s ROM during the manufacturing process. MAC addresses are unique to the device and are not typically
The MAC address is used for Layer 2 (Data Link) communications between networking devices, and consists of 12
