QNX changes the NIC ID?

Hi all:
It sounds strange enough,but it really happened to me.In windows the
winipcfg reports the adapter address as “00-10-a4-8c-6d-c3” ,but the qnx
nicinfo reports the node id as “00-84-00-80-01-80”.I’m suffering from
having to band the different IDs with my ip on the route server when I
am in different OS. Can somebody tell me what is wrong?

best regards.
