Mobile Internet protocol

The Internet works on a simple principle. The two endpoints are essentially stationary computers. The IP routes the packets of data from source to destination with the help of routers. This forwarding of packets by the routers is done depending upon the contents of their router tables. The router tables maintain the out-bound network interface (i.e., the next hop) information for each destination IP address according to the number of networks to which that IP address is connected. The network number is derived from the IP address by masking off some of the low order bits. The working of the mobile Internet protocol is discussed. This is illustrated as a journey from a source to a destination.
