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]
On some systems, the protocol name may be followed by "4" or "6", depending on whether the protocol is running over IPv4 or IPv6. Local Address – The IP address of the local computer and the port number being used. The name of the local computer that corresponds to the IP address and the name of the port is shown unless the -n parameter is ...
Mac OS X 10.5 and 10.6 implement ECN support for TCP. It is controlled using the Boolean sysctl variables net.inet.tcp.ecn_negotiate_in and net.inet.tcp.ecn_initiate_out . [ 20 ] The first variable enables ECN on incoming connections that already have ECN flags set; the second one tries to initiate outgoing connections with ECN enabled.
In computing, netsh, or network shell, is a command-line utility included in Microsoft's Windows NT line of operating systems beginning with Windows 2000. [1] It allows local or remote configuration of network devices such as the interface .
ifconfig (short for interface config) is a system administration utility in Unix-like operating systems for network interface configuration. The utility is a command-line interface tool and is also used in the system startup scripts of many operating systems. It has features for configuring, controlling, and querying TCP/IP network interface ...
Because of the nature of the NAT, IP addresses on the local computer are not visible on the Internet. All packets leaving or entering the LAN are sent from or to the IP address of the external adapter on the ICS host computer. Typically, ICS can be used when there are several network interface cards installed on the host computer. In this case ...
The Address Resolution Protocol (ARP) is a communication protocol for discovering the link layer address, such as a MAC address, associated with a internet layer address, typically an IPv4 address. The protocol, part of the Internet protocol suite , was defined in 1982 by RFC 826 , which is Internet Standard STD 37.
A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ports.
