Semantic IP

I was reading a paper presented at the IETF 86[1] presented by Mr. Jiang.

And so I decided to write a post about Semantic IP.

Everyone is implementing some semantic in their IP addressing. For example, you can assign the third byte of your IPv4 plan depending on the VLAN ID. You can also make an addressing plan depending on the organization (a subnet for users in France, another for users in UK, .... or a subnet for HR service, a subnet for Marketing service ....).

There is a use case example on IPv6 prefixes in this paper : policing depending on the value of the bits 25 to 28.

Because the size of a prefix increase from IPv4 to IPv6, it'll be interesting to see how it'll go in the future. More characteristics included in prefixes (what kind of profile traffic or security policing to apply?)
