The Ethertype indicates which protocol is encapsulated in the payoad of the Ethernet Frame.
IP
The most known Ethertype is 0800
for Internet Protocol version 4 (IPv4).
In turn, Ethernet encapsulates transport layer protocols such as
- TCP
- UDP
TCP and UDP share a number of ports.
ARP
Address Resolution Protocol allows to find the MAC address associated to a given IP address.
It has Ethertype 0806
.
