IPv6 Internet Concentration Growing Rapidly

Based on analysis of Internet routing table information, the RIPE NCC (the European region Regional Internet Registry) publishes a telling graph regarding the growth in concentration of IPv6 networks in the Internet IPv4/IPv6 mix. The useful graph is interactive, allowing filtering by country, RIR or multiple criteria. I like it so much I've framed it into my website.

It's no surprise that the APNIC region with its relatively scarce IPv4 space especially with respect to its served population, has and continues to lead the pack in terms of percentage of Internet networks (autonomous systems) advertising at least one IPv6 prefix. But all regions trend in a like manner, exponentially higher, approximately doubling in proportion since the beginning of 2010!

Assuming this trend continues as IPv4 space runs out completely, ask yourself if your Internet presence is prepared for this growing proportion of IPv6 users. As I've blogged several times this year and will likely continue to harp on, now is the time to prepare for IPv6 deployment if you aren't already doing so!

IPv6 Business Drivers

I just commented on a Network World article about IPv6. The question was asked regarding the top five business drivers for deploying IPv6 and this was my offering:

In my opinion, these are the top 5 business drivers to deploy IPv6:

1. Remaining open for business on the Internet ubiquitously. With Asia being among the fastest growing region for broadband and mobility subscribers with no remaining IPv4 addresses, you'll need an IPv6 Internet presence to communicate with this soon-to-be-exploding segment of the Internet population. If you do any business on the web (and who doesn't?) you need to deploy IPv6 at least externally.

2. Keeping up or ahead of competition who may be ahead or behind in various stages of IPv6 deployment. Depending on your industry, such "technological leadership" can be positioned as a competitive differentiator.

3. Most operating systems ship with IPv6 today so IPv6 may already be "deployed" at least locally in spots. Improve your visibility to IPv6 addresses in use in your network. While this one isn't necessarily a driver to "deployment" it is a driver to prepare for and learn about IPv6.

4. Ability to support partner connections for those partners requiring IPv6.

5. Support a work environment with opportunity for career growth for your IT/Ops staff in being able to work on "new" technology such as IPv6.

IPAM Book News

I just received my August, 2011 issue of IEEE Communications magazine. I noticed a book review for my IP Address Management Principles and Practice book. I am gratified and humbled by the review which included such comments as, "The book ... provides comprehensive information for practitioners dealing with IP Address Management (IPAM)" and, "whenever one encounters a networking issue (not only basic), an answer ... can be found."

In related news about this book, my publisher informed me that it will be translated for sale in China. With continuing proliferation of communications technology and a virtual lack of IPv4 addresses, hopefully readers in China will be able to learn about IPv6 technology and various techniques for effectively managing it along with related IPAM technologies.

If you've read my book or my Introduction to IP Address Management book, I'd be grateful for your feedback as well, whether good, bad or ugly. Also check out my website for more IPAM resources including technology-specific RFCs and ISC/BIND configuration details for IPv4 and IPv6 DHCP and DNS.

Raising the Roof on the IP Address Ceiling

After half a year of drawn out, down-to-the-wire, insidious infighting, the U.S. government has raised the "debt ceiling," the maximum debt liability permitted for the U.S. Treasury. What had routinely been a relatively easy and trivial task in the past became an outright stare-down to the brink of economic calamity. Nevertheless, with Congressional passage and the President's signature, the "capacity" for debt permitted by the U.S. government had been raised.

If only the capacity of IP address space could be raised as "easily." Some may argue that some of the emails on RIR or IETF email lists rival those of Congressional rhetoric over the last few weeks, but all attempts to raise IPv4 capacity have been unsuccessful. This is largely due to the fact that IP address capacity is plentiful in the form of IPv6 address space. Any steps to squeeze out IPv4 space will only postpone the inevitable: IPv6 is required to meet the ever-increasing demand for IP addresses. So instead of raising the ceiling, the Internet added a second floor, which itself has a very high ceiling!

With the Asia Pacific region down to its last remaining /8 block of IPv4 space, we've nearly hit the capacity ceiling for IPv4. Internet users in this half of the world will be among IPv6 early adopters from an end user perspective. Will these users be able to communicate with you and vice versa? It's time to think through the implications and to begin planning for IPv6 deployment.
