FCs). The development and the planning of the Internet is performed by a number of non-profit organisations including the Internet Society, Internet Architecture Board, Internet Engineering Task Force and the Internet Engineering and Planning Group.An IP address is a 32 bit number usually represented using dotted decimal notation where each of the four bytes are represented as decimal numbers separated by dots, e.g. 138.77.1.1. Every machine on the Internet has both an IP address and a fully qualified hostname. All transmission of information on the Internet uses the IP address. Hostnames are used by human beings. Name resolution, the act of converting a hostname to an IP address, is performed using a combination of the file /etc/hosts and the domain name service.Routing is the process of deciding which route a packet of information will use to reach its destination. Each machine on the Internet maintains a routing table that defines where it will route packets. Under UNIX the routing table can be viewed using the netstat command. The route a packet follows can be viewed using the traceroute command. Routing tables are either createdstatically, or by the systems administrator configuring the system, using the startup or configuration fiels, to used a pre-defined, unchanging route.dynamically.There are protocols, part of TCP/IP, that will dynamically modify the routing table in response to events.Adding a host to the network requires obtaining, installing and configuring the necessary network hardware, gather the required information including IP address and hostname of the new host, the gateway and the name server, the network address and the subnet mask, modify the appropriate configuration and startup files with that information, make sure the new host has an entry in the domain name service, test the connection....
