Most IPv4 hosts use link-local addressing only as a last resort when a DHCP server is unavailable. More commonly addresses are assigned by a DHCP server, often built into common networking hardware like computer hosts or routers. For link-local addressing, IPv4 uses the special block 169.254.0.0 / 16, while IPv6 hosts use the prefix fe80:: / 10. Mechanisms were introduced to handle this task automatically, and both IPv4 and IPv6 now include systems for address autoconfiguration, which allows a device to determine a safe address to use through simple mechanisms. On some networks, there is a central authority that assigns these addresses as new devices are added. Hosts on a network must be assigned IP addresses that uniquely identify them to other devices on the same network. Efforts to automate maintenance of this database, led to the introduction of a number of new protocols providing automated services, such as the Dynamic Host Configuration Protocol (DHCP). On Internet Protocol (IP) networks, the Domain Name System database for a network was initially maintained manually by a network administrator. Users could look up any device on the network with the application Chooser, which filtered names based on the device type. NBP included not only a name but the type of device and any additional user-provided information such as its physical location or availability. Network addresses were automatically selected by each device using a protocol known as AppleTalk Address Resolution Protocol (AARP), while each machine built its own local directory service using a protocol known as Name Binding Protocol (NBP). Macs, as well as other devices supporting the protocol, could be added to the network by simply plugging them in all further configuration was automated. for the early Macintosh computers in the 1980s. LAN systems tended to provide more automation of these tasks so that new equipment could be added to a LAN with a minimum of operator and administrator intervention.Īn early example of a zero-configuration LAN system is AppleTalk, a protocol introduced by Apple Inc. The latter wide area network (WAN) systems tended to have centralized setup, where a network administrator would manually assign addresses and names. The names and addresses are then automatically entered into a directory service.Įarly computer networking was built upon technologies of the telecommunications networks and thus protocols tended to fall into two groups: those intended to connect local devices into a local area network (LAN), and those intended primarily for long-distance communications. These systems automatically give themselves common names chosen either by the equipment manufacturer, such as a brand and model number or chosen by users for identifying their equipment. The dynamic nature of modern networks, especially residential networks in which devices are powered up only when needed, desire dynamic address assignment mechanisms that do not require user involvement for initialization and management. Similarly to telephones being labeled with their telephone number, it was a common practice in early networks to attach an address label to networked devices. Network routers examine these addresses to determine the best network path in forwarding the data packet at each step toward its destination. Every packet contains the source and destination addresses for the transmission.

In modern networking protocols, information to be transmitted is divided into a series of network packets. This is similar to the telephone network which assigns a string of digits to identify each telephone.
Zeroconf is built on three core technologies: automatic assignment of numeric network addresses for networked devices, automatic distribution and resolution of computer hostnames, and automatic location of network services, such as printing devices.Ĭomputer networks use numeric network addresses to identify communications endpoints in a network of participating devices. Without zeroconf, a network administrator must set up network services, such as Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS), or configure each computer's network settings manually.

It does not require manual operator intervention or special configuration servers. Zero-configuration networking ( zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected.
