     The pseudo header conceptually prefixed to the UDP header contains the source address, the destination address, the protocol, and the UDP length. This information gives protection against misrouted datagrams.

• Although the specifications of the Internet Protocol say that datagrams are what pass through the network, the word packet is more commonly used.
