Networking Terminology
The following are descriptions of some important IPv6 networking terms.
Node
A node is a device that implements IP on the network. A node can be a
host or a router.
A local node (or host) is the computer (or host) where you have logged-in.
A remote node is a computer on the IP network where you are not logged
in. A remote node does not have to be directly attached to your terminal.
Router
A router is a node that forwards IP packets not explicitly addressed to
itself. It is a device that can forward packets between two or more IP
networks. An IPv6 router can advertise prefixes. IPv6 router guidelines
are beyond the scope of this manual. Refer to RFC 2461 for IPv6 router
guidelines.
Tunnel
A tunnel is a forwarding path between two nodes on which the payloads
of packets are original packets.
Host
A host is any node that is not a router.
Network Interface Name
A network interface is a communication device through which
messages can be sent and received. An IPv6 address is associated with
an interface name. Find the interface name(s) for a network interface by
running the lanscan command and looking at the “Net-Interface Name
PPA” field. For example,
