In the routing of messages from one internet module to another,
datagrams may shortage to oppose a network whose zenith parcel gauge 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.
In support of admonition, a TCP module would call on the internet module to adopt a TCP length (including the TCP header and drug statistics) as the evidence
portion of an internet datagram. The TCP module would minister to the addresses and other parameters in the internet header to the internet module as arguments of the call. The internet module would then conceive an internet datagram and style on the local network interface to post the internet datagram.
The model of action is that an internet module resides in each body employed in internet communication and in each gateway that interconnects networks. These modules share common rules on
interpreting address fields and since fragmenting and assembling internet datagrams. In supplement, these modules (especially in gateways) secure procedures as a remedy for making routing decisions and other functions.
This specific network interface creates a local network header and attaches the datagram sending the result to the destination host. At this stopping-place host the datagram is stripped of the local lattice-work
header not later than the local network interface and handed to the internet module.
