Are ARP tables stored within nodes?

The assertion that ARP tables are stored within nodes is accurate. Address Resolution Protocol (ARP) is a network protocol used to find the hardware address (MAC address) associated with a given IP address within a local area network. Each device or “node” that operates within a network maintains an ARP table to keep track of the mappings between IP addresses and MAC addresses.

When a device needs to communicate with another device on the same subnet, it checks its ARP table to see if it already has the MAC address corresponding to the target IP address. If the entry is not found, an ARP request is broadcasted to the network to discover the MAC address. The response is then cached in the ARP table for future use, which helps to reduce the number of ARP requests and improves network efficiency.

This means that all nodes—be they computers, printers, servers, or network devices like switches and routers—store their own ARP tables locally. This is essential for the proper functioning of network communication within a local environment. Thus, the statement regarding the storage of ARP tables in nodes is true.
