IPv4-ocolypse has arrived!

By Dale Reagan | February 5, 2011

The last /8s for Internet IP address have been released to the official registries – soon, it will not be possible to get a new IPv4 assigned ‘Internet Address’…

Should we be concerned? IMO – no & yes:

Simple Summary/Background –  from Wikipedia

“Internet Protocol version 6 (IPv6) is a version of the Internet Protocol (IP) that is designed to succeed Internet Protocol version 4 (IPv4). The Internet operates by transferring data in small packets that are independently routed across networks as specified by an international communications protocol known as the Internet Protocol. Each data packet contains two numeric addresses that are the packet’s origin and destination devices. Since 1981, IPv4 has been the publicly used Internet Protocol, and it is currently the foundation for most Internet communications. The Internet’s growth has created a need for more addresses than IPv4 has. IPv6 allows for vastly more numerical addresses, but switching from IPv4 to IPv6 may be a difficult process.”

Don’t I need to run IPv6 on my PC?

No (well, at least not now…); eventually, you may need IPv6 for your edge devices (cable modem, DSL modem, other network devices directly attached to the Internet or other public networks.)  Your home or business ISP could resolve the issue by requiring IPv6 edge-connection devices; such devices could manage (via NAT or other means) any network-level-translation required for devices on your internal network(s).  Provided that they have a ‘IPv6 smart’ network edge connection then there should be no need for end users to contend with this issue (at least, no yet.)  I will guess that it will be several years (if ever) before IPv4 protocols are relegated as un-supported Internet traffic…

At this time, while there may be some instances where IPv6 may be useful for end-users, for the most part there is no real need (for internal, local networks, or private networks) and it will simply complicate/further expose PCs and other non-public network devices to abuse/hacking…

Ok, what about my web (or other) server that is accessible on the public Internet?

The Internet Society provides additional information on this issue (snippet below):

World IPv6 Day

On 8 June, 2011

How to Participate

Internet users will not need to do anything different on World IPv6 Day. Web services, Internet service providers, and OS manufacturers will be updating their systems to ensure Internet users enjoy uninterrupted service. In rare cases, users may still experience connectivity issues when visiting participating Websites. Users can visit an IPv6 test site to check if their connectivity will be impacted. If the test indicates a problem, they can disable IPv6 or ask their ISPs to help fix the problem.

Website Owners

If you’d like to bring your company’s website online using IPv6 during the World IPv6 Day you’ll need to make it IPv6 accessible using dual stack technology and provide a AAAA record for the site. IPv4 websites will of course continue to be accessible over IPv4 during the event…

This is a 24 hour event June 8, 2011, from 0000 to 2359 UTC. Websites will be operating over IPv6 for 24 hours on this date…

As always, your opinions and mileage should vary, at least a little… 🙂
