Addressing in the Internet
There was a side meeting on Internet Addressing at IETF-112 this week, discussing potential gaps in Internet Addressing and potential use cases that would suggest new addressing structures.
Looking at the realities in the Internet today, I do not think that actual relevant use cases and current issues in the Internet are served well by just a new addressing approach for the Internet Protocol. Instead I believe that there needs to be architectural discussion first – and addressing might eventually fall out as a result.
