The Internet Protocol Journal, Volume 11, No. 4

From the Editor

Response to our use of a new printing paper has been very positive, so we will continue to use the uncoated and recycled Exact® paper introduced with our September 2008 issue. We are still interested in hearing your feedback on the paper, as well as any other aspect of this journal. Send your comments to: ipj@cisco.com

The last decade has seen many developments in the area of wireless networking technologies. Wireless Internet access is now available in thousands of locations ranging from private homes to hotels, trains, airplanes, ships at sea, and even entire cities. Wireless systems, specifically Bluetooth, are also used for short-range device connectivity such as between a mobile phone and a headset, while WiMAX systems are being deployed for larger area coverage. In our first article, T. Sridhar gives an overview of Wi-Fi, Bluetooth, and WiMAX.

As stated in our previous issue, the topic of IP Version 4 address exhaustion and migration to IP Version 6 is being debated in many Internet-related organizations, including the IETF, Internet Corporation for Assigned Names and Numbers (ICANN), and the Regional Internet Registries (RIRs). In our last issue, Geoff Huston outlined the history of IPv4 address depletion. This time we bring you the first in a two-part series of articles entitled "The End of Eternity." The article is by Niall Murphy and David Wilson. Part Two will follow in our March 2009 issue. As you will see from our "Letters to the Editor," views on the right way to tackle the address exhaustion and protocol migration challenge abound, and I predict we will carry yet more articles on this topic in future issues.

Just over 10 years ago, Jonathan B. Postel, Internet pioneer and a key player in many core Internet activities, passed away. In this issue we bring you a remembrance article written by another Internet pioneer, Vint Cerf. In connection with this anniversary, special events were held in Minneapolis in conjunction with the 73rd meeting of the IETF. The Jonathan B. Postel Service Award for 2008 was awarded to EsLaRed of Venezuela by a committee of former award winners. You will find more information about the award in our Fragments section.
