Host Identity Protocol (HIP)

* Provides:
o Fast mobility
o Multi-homing
o Support for different addressing schemes
+ Transparent IPv4 to IPv6 migration
o Security
+ Anonymity
+ Secure and authenticate datagrams

* A public key used to identify an end-host
* A 128-bit host identity tag (HIT) used for system calls
o HIT is a hash on public key
o Global scope
* A 32-bit local scope identifier (LSI) for IPv4 compatibility
