A Rough Guide to Address Exhaustion by Geoff Huston

By September 28, 2010 Governance No Comments

Geoff Huston imageWith 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?
