If the IP addresses of the network-linked devices change, ARP entries can get corrupted or expired, and new entries may not always overrule the database’s expired entries.Īs a result, it may impact network performance and may cause loading or connectivity problems. It contains a list of known IP addresses and their MAC addresses.ĪRP request is a broadcast, and ARP reply is unicast. When our systems find the MAC addresses for the particular IP address using ARP protocol, they will be stored in a table for future use.

Instead of asking the router every time where the particular device is located and what its mac address is, our system would just connect using the previously resolved IP address. This protocol works between the data link layer and network layer. This article will look at how to check and clear the ARP cache in the different operating systems.ĪRP stands for Address Resolution Protocol, which is responsible for discovering MAC addresses and mapping them to IP addresses in order to communicate successfully with other systems on the local network. Misconfigured or expired ARP cache entries in the system might be one of the reasons for network connectivity problems.Īre you aware that clearing the ARP cache in your system may fix loading problems and connectivity errors?
