In theory, no, not necessarily, since ARP is flexible enough to be used to discover or describe a connection between other kinds of addresses, which don’t have to be the same lengths as IPv4 and Ethernet addresses.

What sets ATM apart from Ethernet is the size of its what?
Its fixed packet size.
Differences between arp packet transmission and ip packet transmission?
an arp (address resolution protocol) comes into picture when we have the ip address of our destination but we dont know the mac address of our destination.Normally when we open a web site this is the process which takes place.IP packet transmission comes after arp when the destination mac address is obtained after arp request.so an ip packet contains both source & destination IP & mac addr.
What is gratuitous ARP?
Gratuitous in this case means a request/reply that is not normally needed according to the ARP specification (RFC 826) but could be used in some cases. A gratuitous ARP request is an AddressResolutionProtocol request packet where the source and destination IP are both set to the IP of the machine issuing the packet and the destination MAC is the broadcast address ff:ff:ff:ff:ff:ff. Ordinarily, no reply packet will occur. A gratuitous ARP reply is a reply to which no request has been made.
How is ARP reply message different from that of ARP request message?
An ARP request is a broadcast Ethernet packet, that is, a packet sent onto the local physical network that all attached devices will receive. A device sends an ARP request to make the query "what is the MAC address (a.k.a. hardware address, link layer address, etc.) of this IP address (a.k.a Layer 3 address, logical network address, etc.)?" An ARP reply is an unicast Ethernet packet, sent from the device that currently owns the specified IP address, back to the device which sent the ARP request. That is, no other device will receive this packet. The ARP reply answers the requester's question, saying "IP address x.x.x.x is associated with MAC address xx:xx:xx:xx:xx:xx".
What is an ARP request?
ARP is a protocol that maps MAC addresses to IP addresses for packet delivery and for finding out which device in a LAN has a given IP address.
What is the purpose of an arp request?
The purpose of an arp request is to map an IP address to a MAC address for the link layer to transmit a packet. For example, ARP will get a request to map 1.2.3.4 to a MAC address 12:fd:23:gf .Then ARP will cache the address mapping that next time an arp request doesnt need to happen
What is an arp request packet for?
ARP stands for Address Resolution Protocol. This is IP's way of requesting a MAC address (or hardware address) from a host located at a certain IP address. In order for a host on a network to send a unicast packet across the network, it must know both the source and destination MAC addresses. ARP is used to obtain a MAC address similar to the way DNS is used to obtain an IP address from a domain name (www.anydomain.com).
How many computers can access to the single computer on the network?

How many MB equals 1 packet?
The size of a packet can vary depending on the network protocol being used. In general, a typical Ethernet packet is around 1500 bytes, which is equal to 0.0015 megabytes (MB). Therefore, 1 packet is approximately equal to 0.0015 MB.
What is the minimum maximum size of ICMP packet?
The minimum size of an ICMP packet is 8 bytes, which includes the 8-byte ICMP header without any additional data. The maximum size of an ICMP packet is 65,535 bytes, which includes the maximum payload that can be carried within an IPv4 packet.
What is the typical yeast packet size used in baking recipes?
The typical yeast packet size used in baking recipes is 7 grams.
What are the functions of ARP?
Address Resolution Protocol (ARP) serves to map IP addresses to their corresponding MAC (Media Access Control) addresses within a local network. When a device needs to communicate with another device on the same network, ARP broadcasts a request packet asking, "Who has this IP address?" The device with the matching IP responds with its MAC address, allowing the original device to establish a direct connection. Additionally, ARP maintains a cache of these mappings to reduce the need for repeated requests, thereby enhancing network efficiency.
