My point is that if my host doesn't configure the peer_HIT_TO_IP map, hipd
would trigger the query for DNS when I ping6 the peer HIT.
But when I ping6 the peer HIT, hipd doesn't send the query or trigger base
exchange.Do I have to configure the map in the /etc/hosts and/or
/etc/hip/hosts files before I want to communicate with peer host.
