What layer does ARP operate at?

ARP is protocol that doesn't fit nicely into the OSI model. It's not a layer two protocol because it utilizes Ethernet_II (Data Link) to get around with broadcast addresses (FF:FF:FF:FF:FF:FF). It's also not a layer three protocol because it doesn't provide routing capabilities. It maps layer 2 addresses to corresponding layer 3 addresses. So you could say it's 2.5. It is encapsulated within Ethernet_II frames.

What protocol used when two host has same ip address?

When two hosts have the same IP address on a network, it can lead to an IP address conflict, causing connectivity issues for both devices. The Address Resolution Protocol (ARP) is often involved in detecting these conflicts, as it maps IP addresses to MAC addresses. Network administrators typically resolve the conflict by reconfiguring one of the devices to use a unique IP address. Additionally, Dynamic Host Configuration Protocol (DHCP) can help prevent such conflicts by dynamically assigning unique IP addresses to devices on a network.


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 are two features of ARP?

Address Resolution Protocol (ARP) primarily features two key functionalities: it maps IP addresses to MAC addresses, enabling devices on a local network to communicate effectively. Additionally, ARP operates within a local area network (LAN) and utilizes broadcast messages to discover the MAC address corresponding to a specific IP address, facilitating the transmission of data packets between devices.


Is ARP the core protocol responsible for logical addressing?

The structure of the question is meant to trick you because 'logical addressing' is being used loosely. Technically, IP is the CORE protocol responsible for logical addressing. ARP is the network layer protocol that is used to discover the identity(physical address) of a machine whose IP address you know. Very briefly, it does this by creating a database that maps the MAC address to the (hosts') logical address provided.


What is the difference of ARP tables and routing tables?

ARP tables and routing tables serve different purposes in network communication. An ARP (Address Resolution Protocol) table maps IP addresses to MAC addresses within a local network, enabling devices to identify each other's physical hardware addresses. In contrast, a routing table contains information on how to forward packets to different networks, detailing the paths to various IP address ranges and the next-hop routers. Essentially, ARP tables facilitate local address resolution, while routing tables guide packet forwarding across broader networks.
