This portion is unclear to me; could you shed some light ?
Do you mean:
1. on linux there is a principal IP address that is assigned to a
node regardless of NIC due to the implementation of ARP etc.
2. on linux there is some magic IP *number* that is assigned to a
node; and IP addresses are assigned to individual NICs.
-> if so, what is a IP number?
