A Rough Guide to Address Exhaustion by Geoff Huston

With IPv4 addresses nearing exhaustion, internet and IPv4/6 expert Geoff Huston has posted an article on his blog looking at a set of answers to the most common questions he has been asked on this topic in recent times.Issues looked at are:

  • What’s the most significant challenge to the Internet today?
  • What is an “IP Address” and why is it so important?
  • Why are we running out of addresses?
  • When will we run out?
  • What’s the plan?
  • How many addresses are in IPv6?
  • How do we transition to IPv6?
  • When my computer supports IPv6 can I return my IPv4 address?
  • What needs to be done to transition the network to IPv6?
  • How long do we expect this dual stack transition to take?
  • What about “address sharing” in IPv4? Why do we need IPv6 anyway, given that we could simple share addresses in IPv4?
  • This all sounds like a terrible problem. Was this whole global “experiment” with the Internet all one big mistake? Should we have looked elsewhere for a networking technology for computers back in the 1990’s?

Is the Transition to IPv6 a "Market Failure?"

Geoff Huston writes: Many views of the transition to IPv6 assume that the combination of the factors of the imminent exhaustion of the unallocated pool of IPv4 addresses and the conventional dynamics of an open competitive marketplace in the ISP sector will be sufficient to propel the transition to IPv6. The question I would like to pose here is: Is this an appropriate view of the transition to IPv6? An alternative view is that this transition to IPv6 has already stalled over the past decade, and we should be prepared to view the current situation as an instance of a “market failure” in economic terms, where the transition will require the impetus of some form of response associated with the distribution of a “public good”, and that conventional market dynamics are in and of themselves incapable of sustaining such a transition.
