What is the size of an Ethernet frame carrying a ARP packet?

What is the size of an Ethernet frame carrying an ARP packet of size 28 bytes? An Ethernet frame contains Preamble, SFD, destination address, source address, length, data padding and CRC.

What type of packet is an ARP request?

ARP Packets. ARP uses packets, but these are not IP packets. ARP messages ride inside Ethernet frames, or any LAN frame, in exactly the same way as IP packets.

How ARP packets work?

ARP broadcasts a request packet to all the machines on the LAN and asks if any of the machines are using that particular IP address. When a machine recognizes the IP address as its own, it sends a reply so ARP can update the cache for future reference and proceed with the communication.

Is ARP an IP packet?

While a standard ip packet / frame has different purposes – carry data for one, using Ip addresses for identifying end points. 4. However, an ARP packet is trying to find information about the point using the IP address. Therefore it is different from a standard IP packet.

What protocol number is Arp?

The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite . ARP was defined in 1982 by RFC 826, which is Internet Standard STD 37.

What is a packet format?

A network packet is a formatted unit of data carried by a packet-switched network. A packet consists of control information and user data, which is also known as the payload. Control information provides data for delivering the payload, for example: source and destination network addresses, error detection codes, and sequencing information.

What is a packet structure?

Structure of a packet. a packet on a network consists of 3 parts, the header, payload and trailer. The header contains instructions about the data carried by the packet, the payload is the applications data and the the trailer tells the receiving device that it has reached the end of the packet.
