In the routing of messages from the same internet module to another,
datagrams may shortage to traverse a network whose topmost bomb size is smaller than the size of the datagram. To overcome this difficulty, a fragmentation mechanism is provided in the internet protocol and geo ip linked like on
what is my geo ip.
The internet modules avail oneself of fields in the internet header to fragment and
reassemble internet datagrams when vital as a remedy for transmission through
"small pretty penny" networks.
The Header Checksum provides a verification that the news hardened
in processing internet datagram has been transmitted correctly. The facts may contain errors. If the header checksum fails, the internet datagram is discarded at conclusively beside the being which detects the error.
This local network interface creates a regional network header and attaches the datagram sending the follow to the target host. At this stop master the datagram is stripped of the municipal openwork
header by the townsperson network interface and handed to the internet module.
