(Address resoultion protocol) The term address resolution refers to the process of finding an address of a computer in a network. The address is “resolved” using a protocol in which a piece of information is sent by a client process executing on the local computer to a server process executing on a remote computer. The information received by the server allows the server to uniquely identify the network system for which the address was required and therefore to provide the required address. The address resolution procedure is completed when the client receives a response from the server containing the required address.
Computers and other network devices on the Internet use an IP address to route your request to the site you’re trying to reach. This is similar to dialing a phone number to connect to the person you’re trying to call. Thanks to DNS, though, you don’t have to keep your own address book of IP addresses. Instead, you just connect through a domain name server, also called a DNS server or name server, which manages a massive database that maps domain names to IP addresses.
