    As ESP is an encapsulation protocol, a value of 4 is also possible, indicating IP in IP. A value of 41 indicates IPv6 encapsulated in IPv4 , e.g. 6to4 . The value 59 (meaning: No Next Header ) is used for dummy packets, which may be inserted in the stream, and which contents should be discarded.

    A HAIPE is an IP encryption device, looking up the destination IP address of a packet in its internal Security Association Database (SAD) and picking the encrypted tunnel based on the appropriate entry. For new communications, HAIPEs use the internal Security Policy Database (SPD) to set up new tunnels with the appropriate algorithms and settings.
