WHAT IS ARP (ADDRESS RESOLUTION PROTOCOL)?

What is ARP (Address Resolution Protocol)?

ARP is same as Roll Call in school. ARP (Address Resolution Protocol) is how network devices associate MAC (Media Access Control) Addresses with IP (Internet Protocol) addresses. It enables devices on a local computer network to find each-other.

Every networked computer has two addresses known as:
1)      MAC Address
2)      IP Address

MAC (Media Access Control) ADDRESS
               

This address is unique identifier e.g. 00-00-0c-36-12-5d that is usually hard-coded into a NIC (Network Interface Card) by its manufacturer, which is permanent and does not change.
