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.
ifconfig: ip addr, ip link: Address and link configuration route: ip route: Routing tables arp: ip neigh: Neighbors iptunnel: ip tunnel: Tunnels nameif, ifrename: ip link set name: Rename network interfaces ipmaddr: ip maddr: Multicast netstat: ss, ip route: Show various networking statistics brctl: bridge: Handle bridge addresses and devices
One reason for using this could be to make a computer look as though it is multiple computers, so for example you could have one server that is acting as both a gateway (router) and a DHCP server and DNS using three different IP addresses, perhaps with a future plan to use a hardware router and to move the functionality to separate DNS and DHCP ...
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]
Kea is an open-source DHCP server developed by the Internet Systems Consortium, authors of ISC DHCP, also known as DHCPd.Kea and ISC DHCP are both implementations of the Dynamic Host Configuration Protocol, a set of standards established by the Internet Engineering Task Force (IETF).
This method is also variously called static DHCP allocation, fixed address allocation, reservation, and MAC/IP address binding. An administrator maps a unique identifier (a client id or MAC address) for each client to an IP address, which is offered to the requesting client. DHCP servers may be configured to fall back to other methods if this ...
ROCKFORD, Ill. (WTVO) – It’s been 34 years since Macaulay Culkin’s character, Kevin McCallister, made a trip to the supermarket for supplies in the 1990 Chris Columbus film “Home Alone ...
For instance, the active ifconfig directive may be used on NetBSD to specify which of the attached addresses to activate. [18] Hence, various configuration scripts and utilities permit the randomization of the MAC address at the time of booting or before establishing a network connection. Changing MAC addresses is necessary in network ...
