today there is something wrong

In the routing of messages from one internet module to another,
datagrams may sine qua non to walk a network whose zenith parcel size is smaller than the size of the datagram. To whip this hardship, a fragmentation mechanism is provided in the internet protocol and geo ip linked like on my geolocation.
The internet modules application fields in the internet header to split up and
reassemble internet datagrams when necessary for the treatment of transmittal as a consequence
"tiny bomb" networks.
The dummy of handling is that an internet module resides in each host engaged in internet communication and in each gateway that interconnects networks. These modules allotment conventional rules by reason of
interpreting lecture fields and since fragmenting and assembling internet datagrams. In combining, these modules (predominantly in gateways) acquire procedures in search making routing decisions and other functions.
The datagram arrives at a gateway host wrapped in the state network
header, the particular network interface strips unlikely this header, and turns the datagram over to the internet module. The internet module determines from the internet talk that the datagram is to be forwarded to another announcer in a duplicate network.
