    - The purpose of using a pseudo-header is to verify that the UDP datagram has reached its correct destination.

    - The UDP header itself specifies only the protocol port number for verifying the destination.

    - UDP on the sending machine computes a checksum that covers the destination IP address as well as the UDP datagram.

    - The pseudo-header is not transmitted with the UDP datagram nor is it included in the length.
