Address translation

Address translation or address resolution may refer to:

• Network address translation
• Address Resolution Protocol or ARP, a computer networking protocol used to find out the hardware address of a host (usually a MAC address), when only the network layer address is known
• Reverse Address Resolution Protocol or RARP, a protocol used to find the network layer address of a host, based only on the hardware address. This protocol has been rendered obsolete by both BOOTP and DHCP
• Domain name system or DNS, which is used to translate network addresses to human-recognizable domain names
• Virtual-to-physical address translation
