IP addresses are designed as topology locator, so that every packet can be routed to its network destination.
However, even in IPv4 era, some network operators have mapped their IP address with certain semantic locally. These kind of mechanism explicitly express the semantic properties of every packet. Consequently, these network operators can inspect the properties of packets easily by mapping the addresses back to semantic. Network operators, who have large IPv6 address space, may also choose to embedded some semantics into IPv6 addresses by assigning additional significance to specific bits within the prefix. draft-jiang-v6ops-semantic-prefix documents a framework method that network operations may use their addresses with embedded semantics. These semantics bits are only meaningful within a single network, or group of interconnected networks which share a common addressing policy. Based on these embedded semantic bits in source/destination addresses, the network operators can accordingly treat network packets differently and efficiently. http://tools.ietf.org/html/draft-jiang-v6ops-semantic-prefix-03 Could you please review this draft and comments? It will help the document become more useful information to be shared.
