WebIP will then look at the packet header to see the protocol number, and it will send the packet payload to the correct transport protocol (TCP, UDP, etc.). The transport protocol will then send the datagram payload to the application registered to it (TCP and UDP use ports for this, other transport protocols may do something else).
