TCP/IP's layers are descriptions of operating scopes (application, host-to-host, network, link) and

detailed prescriptions of operating procedures, data semantics, or networking technologies.

Layering in TCP/IP is not a principal design criterion and in general is considered to be

4

The standard (IEEE 802) format for printing MAC-48 addresses in human-friendly form is

groups of two hexadecimal digits, separated by hyphens (-) or colons (:), in transmission order.

If the least significant bit of the most significant octet of an address is set to 0 (zero), the frame is meant to reach

.

7

If the least significant bit of the most significant address octet is set to 1, the frame will still be sent only once; however, NICs will choose to accept it based on different criteria than a matching MAC address: for example, based on
