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.
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 Unix-based operating systems, Mac OS X also uses ifconfig for more direct control over network interfaces, such as configuring static IP addresses. The Ifconfig command in Linux ...
Solaris has historically used ifconfig for all network interface configuration, but as of Solaris 10 introduced dladm to perform data-link (OSI model layer 2) configuration, reducing ifconfig's purview to IP configuration. In older Linux distributions, ifconfig, in conjunction with the utility route, was used to connect a computer to a network ...
On Linux and all Unix-like operating systems, the utilities ifconfig and the newer ip (from the iproute2-bundle) are used to configure IEEE 802.3 and IEEE 802.11 hardware. These utilities configure the kernel directly and the configuration is applied immediately. After boot-up, the user is required to configure them again.
The configuration software of choice is then used to configure the persistent configuration which is applied on boot. It is also possible to configure Linux networking ad-hoc using the ip command from the iproute2 package. The following command can be used to configure the route using ip: [10]

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. It does not require manual operator intervention or special configuration servers.
