Host Identity Protocol for Linux

Have you ever wondered why your multimedia streams stop working after you switch to a different network with your laptop? Have you thought about why setting up a server on your home network behind a NAT is so awkward or even impossible? Host Identity Protocol for Linux (HIPL) offers a remedy to these and other problems.
The HIPL Community

HIPL is open-source software for Linux. We are actively improving the software according to feedback from user mailing lists ( We welcome all Linux enthusiasts to the HIPL community, and we are looking for more users and developers.


Host Identity Protocol brings communications privacy and mobility support for existing applications by introducing a new cryptographic namespace. It also allows you to set up servers behind NATs easily. In this article, we discussed how HIP works and how you can install it on your Linux box. We have shown how you can use HIP with Firefox and how to stream video with VLC successfully during network IP address change.
