interfaceId
InterfaceId is a term used in IPv6 networking to describe the 64-bit interface identifier that forms the suffix of an IPv6 address. An IPv6 address is typically divided into a 64-bit network prefix and a 64-bit interface identifier. The combination of the prefix and the interface identifier identifies a particular interface on a network segment, enabling routing and local reachability.
Construction methods for interface IDs have varied. Historically, many implementations derived the interface identifier from the
In operation, the interface identifier enables address autoconfiguration and local communication. Through Stateless Address Autoconfiguration (SLAAC)
Privacy and security considerations are important. Since an interface identifier can reveal hardware or user identity
