What is the Ethernet Type value for IPv4 in hexadecimal?

The Ethernet Type value for IPv4 is represented as 0x0800 in hexadecimal. This value is specified in the Ethernet frame header and is used to indicate the protocol encapsulated within the frame. When a network device receives an Ethernet frame, it looks at the Ethernet Type field to determine how to process the frame's payload; in this case, seeing the value 0x0800 signals it to expect an IPv4 packet.

In contrast, other values in the question correspond to different protocols. For example, 0x0806 represents the Address Resolution Protocol (ARP), while 0x86DD indicates IPv6. The value 0x0801 does not correspond to any standard protocol and is not used in this context. Understanding these values is crucial for network engineers and technicians as they manage and troubleshoot network communications.
