In macOS, the ifconfig command functions as a wrapper to the IPConfiguration agent, and can control the BootP and DHCP clients from the command-line. Use of ifconfig to modify network settings in Mac OS X is discouraged, because ifconfig operates below the level of the system frameworks which help manage network configuration.
ipconfig in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface. [8] For example, you can release and renew an IP address if it happened to be assigned incorrectly by the DHCP server during the automated assignment process. [9] Like most ...
dhcpd (an abbreviation for "DHCP daemon") was a DHCP server program that operates as a daemon on a server to provide Dynamic Host Configuration Protocol (DHCP) service to a network. [3] This implementation, also known as ISC DHCP, is one of the first and best known, but there are now a number of other DHCP server software implementations available.
An early example of a zero-configuration LAN system is AppleTalk, a protocol introduced by Apple Inc. for the early Macintosh computers in the 1980s. 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.
In this example, the default gateway uses the IP address 192.168.4.1, which is resolved into a MAC address with ARP in the usual way. The destination IP address remains 192.168.12.3, but the next-hop MAC address is that of the gateway, rather than of the ultimate destination.
In Linux distributions based on 2.2.x Linux kernels, the ifconfig and route commands are operated together to connect a computer to a network, and to define routes between computer networks. Distributions based on later kernels have deprecated ifconfig and route, replacing them with iproute2. Route for Linux was originally written by Fred N ...
One method of assigning IP addresses is DHCP in which addresses typically are issued by a DHCP server running on one or more hosts. If one of these machines is on the same subnet as its clients, the DHCP server can respond to their broadcast DHCP requests and issue an address. But the DHCP servers may be hosted on a different subnet and, by ...
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
