In tools directory, there is dnshipproxy script, which provides DNS proxy functionality. The script has to be started with root priviledges.
The DNS proxy can read HIT information from HIP hosts files and provide corresponding AAAA records. If it is asked an AAAA record for a FQDN and there is no real existing AAAA for the name, it tries to find a HIP RR for the name. If it finds one, it responds with an AAAA response.
The DNS proxy is meant to be run under DJB's daemontools package http://cr.yp.to/daemontools.html which is also used to provide necessary environmanet variables, see comments in dnshipproxy. It is recommended to use a DNS cache, like http://cr.yp.to/djbdns.html in front of dnshipproxy. The use without DNS cache results in longer look up latencies.
