IPv6 terms

Network node
A network node is a device that is connected to one or more networks via one or more
interfaces.
Router
A network node that forwards IPv6 packets.
Host
A network node that represents an end point for IPv6 communication relations.
Link
A link is, according to IPv6 terminology, a direct layer 3 connection within an IPv6 network.
Neighbor
Two network nodes are called neighbors when they are located on the same link.
IPv6 interface
Physical or logical interface on which IPv6 is activated.
Path MTU
Maximum permitted packet size on a path from a sender to a recipient.
Path MTU discovery
Mechanism for determining the maximum permitted packet size along the entire path from a
sender to a recipient.
LLA
Link local address FE80::/10
As soon as IPv6 is activated on the interface, a link local address is formed automatically. Can
only be reached by nodes located on the same link.
ULA
Unique Local Address
Defined in RFC 4193. Via this address, the IPv6 interface can be reached in the LAN.
GUA
Global Unicast Address Via this address, the IPv6 interface can be reached, e.g. via the
Internet.
Interface ID
The interface ID is formed with the EUI-64 method or manually.
EUI-64
Extended Unique Identifier (RFC 4291); method for forming the interface ID. In Ethernet, the
interface ID is formed from the MAC address of the interface. Divides the MAC address into
the manufacturer-specific part (OUI) and the network-specific part (NIC) and inserts FFFE
between the two parts.
