The KAME project developed a Mobile IPv6 implementation for the FreeBSD and NetBSD platforms. The code is implemented as part of the kernel. In addition to this, several user space programs have been developed for MIPv6 control, for extracting MIPv6 statistics and for dynamic home agent discovery

The implementation follows RFC 3775 and includes functionality for HA, MN and CN (mandatory for an IPv6 implementation that claims to be IPv6 compliant). In addition, KAME supports authentication of messages between a MN and its HA using IPSec.
