Every intermediate node, while forwarding a RouteRequest, enters the previous node address and its BcastID.
A social VPN uses online social networks to distribute public keys and advertise node address to friends.
Once each node acquires the node address (and public keys) of the other node, an IP-to-nodeAddress mapping is created and IP packets can be routed through the VPN tunnel.
"Paths" are often formed by concatenation of node names or node addresses.
These methods allow the detection of the position of slave nodes on the LIN bus and allow the assignment of a unique node address.
The result of this process is the IPv6 link-local solicited node multicast address that the Neighbor Solicitation packet is sent to.
In this scheme, IPv4 and IPv6 would have to be classed with X.25 as subnet access protocols because they carry interface addresses rather than node addresses.
Hosts have a 48-bit node address which by default is set to the network interface card's MAC address.
The node address is appended to the network address to create a unique identifier for the host on the network.
As the node address is usually identical to the MAC address of the network adapter, the Address Resolution Protocol is not needed.
