network segment is always /64. That’s 2(128-64) or 264 or 18 billion addresses. This may seem wasteful; however its inline auto configuring IPv6 addresses from device MAC addresses on a local network segment. Even with this address allocation, it still provides the Internet with a massive increase in address space. If you want to delve more into this subject, A Hurricane Electric network engineer can help you understand this issue.

Native IPv6 is available on Hurricane Electric version-3 web servers

At this point in time, the version-3 web servers have the Apache, SSH/SFTP, and POP3/IMAP portions validated for IPv6. Hurricane Electric is still testing some additional portions of the system.

Hurricane Electric operates a Free IPv6 Tunnel Broker: http://tunnelbroker.net

For networks and servers not connected to the Hurricane Electric network and that don’t have easy access to native IPv6 networks today, Hurricane offers a free tunnel broker service. The service enables you to reach the IPv6 Internet by tunneling over existing IPv4 connections from your IPv6 enabled host or router to the Hurricane Electric IPv6 backbone.

The Hurricane Electric tunnel service is oriented towards developers and experimenters that want a stable tunnel platform. The web site provides information on setting up tunnels on various platforms, including Windows, Mac OS X, Linux and various router platforms. This can normally be a five minute process.

Hurricane Electric maintains a Global IPv6 Progress Report:

Routing is normally a very transparent operation to an end user. In fact, if routing is working correctly, it never comes up in conversation. During this IPv6 transition process, Hurricane Electric decided that it needed to provide customers with some useful metrics.

Hurricane Electric took a first pass at developing some metrics for global IPv6 deployment. Some of the items measured are: the number of networks running IPv6, the number of IPv6 prefixes with working reverse DNS, the relative performance of IPv6 vs IPv4 as measured by pinging nameservers with both IPv6 and IPv4 connectivity, and the number of Alexa top 500 websites that have added AAAA records so far.


What should you do right now?

Forward this document to other people within your company who need to be more aware of IPv6.

What should you do in the upcoming months?

If you are a Hurricane Electric transit, colocation, or root dedicated server customer then learn about how to configure your routers and servers for IPv6 and then try setting up a server with basic IPv6 connectivity so that you can ping it and access it via HTTP and SSH.
