) the Ifconfig (8) command is typically run at boot time to configure each interface on the host. Because the dial-up interface may be plugged in and out frequently (such as a slip link), the ifconfig must run in some way each time the line is switched on and off. How this process is done depends on the slip software used.(2) the Netstat (1) command provides the interface information on the system. The-I parameter prints out the interface information, and the-n parameter prints out the

when using multicast addressing.Under the control of the software, the protocol stack in each Internet host can join or leave a multicast group. When a host sends data to a group, it creates a datagram that uses the (unicast) IP address as the source address, using the multicast IP address as the destination address.

This approach allows site administrators to compromise on the number of subnets and the number of hosts expected for each subnet, reducing coordination with other sites.It's like the school does not assign classrooms to each class, but instead throws the task to the college to deal with.

Internet Group Management Protocol (IGMP), which allows all systems on a physical network to know the multicast group in which the host is currently located. Multicast routers need this information to know which ports multicast data packets should be forwarded. IGMP is defined in RFC 1112. IGMP has a fixed message length and no data is available.

Definition:The IP protocol is located at the network layer of the OSI network model. It provides a fast but unreliable service, which means that it does not guarantee that IP datagram can successfully reach the destination.TCP, UDP, ICMP, and IGMP data are transmitted in IP datagram format.
