Zero configuration networking Wikipedia. Zero configuration networking zeroconf is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite TCPIP when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers. 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 computers network settings manually. 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. BackgroundeditComputer networks use numerical network addresses to identify communications endpoints in a network of participating devices. This is similar to the telephone network, which assigns a string of digits to identify each telephone. In modern networking protocols, information to be transmitted is divided into a series of network packets. Every packet contains the source and destination addresses for the transmission. Network routers examine these addresses to determine the best network path in forwarding the data packet at each step toward its destination.

Bonjour The mDNSResponder. Bonjour for Windows service, which is Apples Zero Configuration Networking. 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. The dynamic nature of modern networks, especially residential networks in which devices are powered up only when needed, requires ad hoc, dynamic address assignment mechanisms that do not require user involvement for initialization and management. 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 names and addresses are then automatically entered into a directory service. The early history of computer networking 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. Wide area network WAN systems tended to have centralized setup, where an authority would assign addresses and names, often by a network administrator using manual means. Bonjour For Windows 8' title='Bonjour For Windows 8' />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. An early example of a zero configuration LAN system is Apple. Talk, a protocol introduced by Apple Inc. Bonjour For Windows 8' title='Bonjour For Windows 8' />Macintosh computers in the 1. Macs, as well as other devices supporting the protocol like the Apple IIGS and a variety of printers and file servers, could be added to the network by plugging them in, all further configuration was automated. Network addresses were automatically selected by each device using a protocol known as AARP, while each machine built its own local directory service using a protocol known as NBP. NBP included not only a name, but the type of device and any additional user provided information like its physical location or device status. Users could look up any device on the network with the application Chooser, which filtered names based on the device type. On Internet Protocol networks, the Domain Name System was initially maintained manually by a network administrator. This led to the introduction of a number of new protocols providing automated services, such as the Dynamic Host Configuration Protocol DHCP. Address selectioneditInternet protocols assign objects in the network one or more unique IP addresses that identify them to other devices on the same network. These addresses operate in a fashion similar to telephone numbers, allowing devices to connect to each other by identifying the remote device by its address in the same way that a telephone call is connected by dialling in a telephone number.

Mechanisms were introduced to handle this task, and both IPv. IPv. 6 now include systems for address autoconfiguration, which allows a device to determine a safe address to use through simple mechanisms. For link local addressing, IPv. RFC 3. 92. 7 while IPv. More commonly, in modern networks addresses are assigned by a DHCP server, often built into common networking hardware like computer hosts or routers. Most IPv. 4 hosts use link local addressing only as a last resort when a DHCP server is unavailable. An IPv. 4 host otherwise uses its DHCP assigned address for all communications, global or link local. One reason is that IPv. Another is that not every IPv. DNS, so discovering the autoconfigured link local address of another host on the network can be difficult. However, discovering the DHCP assigned address of another host also requires either distributed name resolution or a unicast DNS server with this information, and some networks feature DNS servers that are automatically updated with DHCP assigned host and address information. IPv. 6 hosts are required to support multiple addresses per interface moreover, every IPv. IPv. 6 hosts may additionally self configure additional addresses on receipt of router advertisement messages, thus eliminating the need for a DHCP server. Both IPv. IPv. 6 hosts may randomly generate the host specific part of an autoconfigured address. IPv. 6 hosts generally combine a prefix of up to 6. EUI 6. 4 derived from the factory assigned 4. IEEEMAC address. The MAC address has the advantage of being globally unique, a property inherited by the EUI 6. The IPV6 protocol stack includes duplicate address detection to avoid conflicts with other hosts. In IPv. 4, the method is called link local address autoconfiguration. However, Microsoft refers to this as Automatic Private IP Addressing APIPA3 or Internet Protocol Automatic Configuration IPAC supported since at least Windows 9. Name service discoveryeditInternet protocols use IP addresses for communications, but these are not really human readable IPv. To address this issue, the internet has long used the Domain Name System DNS, which allows human readable names to be associated with IP addresses, and includes code for looking up these names from a hierarchical database system. Users type in domain names, such as example. DNS software looks up in the DNS databases to retrieve an IP address, and then hands off that address to the networking software for further communications. Looking up a DNS address requires the IP address of the DNS server to be known. This has normally been accomplished by typing in the address of a known server into a field in one of the devices on the network. In early systems this was normally required on every device, but this has been pushed up one layer in the hierarchy to the DHCP servers or wide area network devices like cable modems that receive this information from their IP provider. This has reduced the user side administration load and provides a key element of zero configuration access. DNS was intended to provide uniform names to groups of devices within the same administration realm, such as example. Assigning an address to a local device, e.
