Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems. Bonjour can also be installed onto computers running Microsoft Windows.

A reverse DNS lookup is a query of the DNS for domain names when the IP address is known. Multiple domain names may be associated with an IP address. The DNS stores IP addresses in the form of domain names as specially formatted names in pointer (PTR) records within the infrastructure top-level domain arpa. For IPv4, the domain is in-addr.arpa.
Computers can maintain lists of known addresses, rather than using an active protocol. In this model, each computer maintains a database of the mapping of Layer 3 addresses (e.g., IP addresses) to Layer 2 addresses (e.g., Ethernet MAC addresses). This data is maintained primarily by interpreting ARP packets from the local network link.
In computer networking, it refers to processes used to obtain the assigned IP addresses needed to communicate with devices whose host or domain names are known. Examples include the Domain Name System (DNS), Network Information Service and Multicast DNS (mDNS).
Multicast DNS (mDNS) is a computer networking protocol that resolves hostnames to IP addresses within small networks that do not include a local name server.It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
MAC addresses need to be individually configured on the servers by an administrator. RARP is limited to serving only IP addresses . Reverse ARP differs from the Inverse Address Resolution Protocol (InARP), which is designed to obtain the IP address associated with a local Frame Relay data link connection identifier. [ 2 ]
