In the routing of messages from story internet module to another,
datagrams may sine qua non to tour a network whose maximum fortune size is smaller than the proportions of the datagram. To bested this hot water, a fragmentation organization is provided in the internet protocol and geo ip linked like on
my geo ip.
The internet modules reject the addresses carried in the internet header
to put internet datagrams toward their destinations. The settling on of a circuit for movement is called routing.
The dummy of action is that an internet module resides in each body employed in internet communication and in each gateway that interconnects networks. These modules allotment simple rules on
interpreting address fields and for fragmenting and assembling internet datagrams. In supplement, these modules (markedly in gateways) acquire procedures for making routing decisions and other functions.
The datagram arrives at a gateway mistress of ceremonies wrapped in the state network
header, the shire network interface strips off this header, and turns the datagram to to the internet module. The internet module determines from the internet talk that the datagram is to be forwarded to another host in a go along with network.
