The main purpose for producing Experimental documents instead of standards track ones are the unknown effects that the mechanisms may have on applications and on the Internet in the large.
HIP continues to separate the roles of identification and location in IP addressing by implementing a host identity namespace based on cryptography.
The protocol also uses the Encapsulating Security Payload (ESP) format for encrypting data, which ensures the integrity and confidentiality of communications.
HIPv2's design enables devices to change networks without losing the session, a crucial advantage for mobile and IoT applications.
This capability to switch networks seamlessly makes HIPv2 well-suited for devices that require constant and reliable connectivity, such as mobile phones and IoT sensors.
