Interface belongs to a single node, any of that node's interfaces' IPv6 addresses of all types are assigned to interfaces, not nodes.Īn IPv6 unicast address refers to a single interface. In IPv6, all zeros and all ones are legal values for any field, (e.g., 'subnet prefix'), it refers to all of the address from the Identifier after the name (e.g., 'subnet ID'), it refers to theĬontents of the named field. When this name is used with the term 'ID' for In this document, fields in addresses are given a specific name, forĮxample, 'subnet'. There are no broadcast addresses in IPv6, their function being Multicast address is delivered to all interfaces
