Google™ to Test IPv6 in June 2011

TCP/IP (Transmission Control Protocol/Internet Protocol) as we all know is the basic communication language or protocol of the Internet. Many years ago the IANA or the Internet Assigned Numbers Authority was formed and was made responsible for the global co-ordination of the Internet Protocol Addressing system. Towards globalizing the IP address system, various research studies were already underway and as we know in development parlance, many versions find their way before a final, usable version is announced and launched. The most commonly known version in our generation happens to be the IPv4 or the Internet Protocol Version 4. IPv1, IPv2 and IPv3 are the three versions that were phased out when IPv4 was universally accepted and launched.

As IPv4 came into the running, both IPv5 and IPv6 developments were on. In the process of IPv5 design, developers and designers realized various difficulties in the introduction of the new version of the IP with the growth of internet usage mushrooming to levels unbelievable. With this, IPv5 was shelved and all efforts were focused towards IPv6. In mid 2010, the American Registry for Internet Numbers announced that the Internet will run out of Internet numbers in about one year’s time on the present protocol. The explosion of data, occurring, mainly due to various applications, equipment, sensors, smart-grids, RFID, bio-metric devices and a horde of such developments connecting to the Internet as well as the phenomenal user generated content growth, is seen as the key factors leading to this situation.

As some archives and articles show, with Internet growing of age and technologies hitherto unimagined, even though the IPv6 is a much, much larger platform than the IPv4, fears of the Y2K episode will have to be shelved and we will have to move on.

It is very interesting to see forces like Google, Facebook, Twitter and others with a vision, convincing market forces and organizations to start using the IPv6 platform. Google took the lead in June 2010 by holding the Google IPv6 implementer’s conference with good participation from one and all. Companies are all getting set to whole heartedly participate in the trial of the IPv6 to begin in June 2011. Google is already taking steps to educate users worldwide regarding the World IPv6 Day towards large scale adoption of the IPv6.

An estimate of IPv4 reaching the limit with technology explosion is anticipated not later than November 2011. With Google and the Android community bringing Internet TV on the convergence platform, you are the best judge, to imagine how far this could be true.

The 6 biggest misconceptions about IPv6

A need to upgrade the currently used IPv4 has been felt for quite some now to handle the wildfire like growth of the network. But experts have tried to justify their refusal to adopt IPv6 by taking support from some preset misconceptions. It is high time that we cleared our minds of these misplaced notions because due to the rapidly growing network we are soon going to fall short of IPv4 addresses.

Amongst the biases the following are the biggest misconceptions that have been doing rounds recently:

Black Marketing of IPv4 Addresses – There is a fear that the introduction of IPv6 will trigger black marketing of IPv4 addresses. In the views of the experts, in anticipation of the rise of this problem, the regional Internet registries have devised legal ways of transferring and selling the unused IPv4 addresses. It is feared that this problem may catch the experts off-guard because not much is being done by the IT departments and vendors towards this. A new policy is being considered by the regional Internet registries that will allow the transfer of IPv4 addresses. One more instance in this case is the step taken by ARIN that has announced that it would make sure that the addresses are used to provide network services and are not hoarded for future use or for black marketing.

IPv6 believed to be more secure – A myth goes around that IPv6 is more secure than IPv4. The reason why this is assumed is that IPv6 was designed with a view to implement the IPsec much more efficiently. But this doesn’t make sure that IPv6 is in itself more secure.

Adoption of IPv6 not yet required – Most of the companies have not yet made any move towards starting development work on IPv6. No amount has been laid aside for investing on this project. A large number of the experts are under the impression that the introduction of IPv6 can be delayed as there is no urgency for its adoption.

IPv4 addresses still available in large numbers – Another misconception is that the IPv4 addresses are still available in plenty. Our thinking whether IPv4 is fast running short of addresses depends on the place where we live and how fast is the rate of growth of the network. A huge shortage in IPv4 addresses has been predicted for the present year. Chris Davis, senior director of corporate marketing communications at NTT America (a leading provider of IPv6 transit and access services in USA), has called this depletion of IPv4 free address pool as a wake-up call.

Internet will be more simple with IPv6 – It is believed that IPv6 will make using Internet much more simple as its introduction will lead to discontinuation of usage of Network Address Translation (NAT) and also the removal of middle boxes, which were being used earlier to prolong the life of IPv4 addresses. But little do they realize that for some time IPv4 and IPv6, both the versions will be put to use simultaneously.

Lucky ones will get hold of the remaining IPv4 addresses – The IANA has already used all the IPv4 addresses in the month of February. Now the remaining addresses will be transferred by the regional Internet registries. According to estimates, the African registry, AfriNIC, is expected to finish last with these addresses. A one-time allotment policy will be followed. The last IPv4 addresses would be shared with multiple users.

World IPv6 Day Trial to be hosted by Google, Facebook, Yahoo

IPv6 is the extended version of IPv4 connectivity and some of the Internet’s most popular web sites such as, Facebook, Google and Yahoo have agreed to participate in the first global-scale trial of IPv6. IPv6 is the long awaited upgrade to the Internet’s main communication protocol known as IPv4. On the World IPv6 Day, participant websites will support native IPv6 traffic on their main web sites on June 8, 2011. Also some of the leading content delivery networks like Akamai and Limelight Networks committed to the IPv6 trial. This trial is being sponsored by Internet society.

Leslie Diagle, the Internet Society’s Chief Internet Technology Officer says ” “It’s an exciting opportunity to take IPv6 for a test flight and try it on for a full 24 hours,” he also mentioned that “Hopefully, we will see positive results from this trial so we will see more IPv6 sooner rather than later.”
It is very necessary to upgrade because Internet is running out of IP addresses using the 30-year-old IPv4 standard. So, they think to motivate using IPv6 now onwards.
As per the statistics, less than 5% of IPv4 addresses are left unallocated to the regional registries. These in turn dole them out to network operators and moreover experts also mention that the free pool of IPv4 addresses will be depleted in a matter of weeks.
The main differences between IPv4 and Ipv6 are as follows. IPv4 uses 32-bit addresses and it can also support 4.3 billion devices connected directly to the internet. IPv6 is better, comparing with IPv4, because it can support a virtually unlimited number of devices directly connected to the internet and uses 128-bit addresses.
World Ipv6 will be very important as it is likely to be a surge of IPv6 traffic across the internet. It is important because only 0.2% of Internet user use IPv6 network according to Arbor Networks. But there are some issues with IPv6 also such as. It is doubtful whether IPv6 will be up to the task of providing efficient performance on such heavy trafficked sites. There may be some sort of slowdowns and a minority of Internet users- 0.05%- will experience slowdowns or may be they have trouble connecting to participating web sites during the trial. It may be because of mis-configured or misbehaving network equipments.
Daigle also mentioned that there may be some individual hiccups for some small access providers or users, but IPv6 is not an experimental technology and also he told he do believe it will work.
Yahoo is also taking this event as a big deal because initially Yahoo was not supporting IPv6. Yahoo said that Participating in World IPv6 Day will allow us to obtain real-life data that we can use to ensure a seamless user experience as we transition to IPv6.

Pro’s and Con’s of Windows 7 Security Features

The new security features of Microsoft Windows 7 allows for better security features which can help the users to segregate each of them and figure out which one is good and bad. The new Windows operating system has been engineered with different features and applications that make it user-friendly and any user’s guide to better computing. Apart from the virtues, it also comes with limitations.

Neil MacDonald gave an insight into the various features of the operating system at the Gartner Summit; Risk Management Summit 2010 last week.

The AppLocker feature that Windows 7 holds proffers the users with an application-control capability, which is inbuilt with the power to prepare a list of applications that and IT manager wants to run. This technique is called “whitelisting” and this type of security control proffers a potential lock-down technique. The source of difficulty is that the applications that are used within organizations by the employees have a tendency to grow. Therefore, there is a necessity to manage the white list over a period of time so that the new list is always updated. MacDonald suggested that third-party security products are a better fit.

MacDonald strained on the fact that the whitelist needs to be cared and fed over time. he noted that there are a number of vendors building their mark in the application-control market. Few names of these vendors include Bit9, McAfee and Bit9.

BitLocker is another potential feature of the operating system that helps to protect system files as well as data. This feature is one of many security features that various businesses are willing to evaluate in Microsoft Windows 7. This feature holds a few minus points: no self-service key recovery, no smart card support for boot drive and no Windows single sign-on.

The license restriction imposes a confinement on operating system virtualization. The operating system does not support non-Windows machines or even Windows mobile.

MacDonald pointed out that Windows 7 BitLocker has not been legally certified under the Federal Governments FIPS 140 program and is on its way to certification.

Other security features as the user-account control imposes restrictions on the ability of applications or the users to make unofficial changes to the system. This feature has been improved to make the prompts insignificant. Unfortunately, it does not superimpose restrictions on a user who is running the system as a standard user from setting up or installing a software.

Direct Access is another Windows 7 security feature, which is an “always-on” VPN client that makes use of IPv6 below to address a workstation that is located in any part of the world, uniquely. Supporting this IPSec tunnel, MacDonald pointed out, can pose problematic for different reasons as there is a lot of complexity especially when organizations do not have an IPv6 network inbuilt.

As far as the most likely software is concerned, Windows Ultimate version is cheaper than Windows 7 Enterprise version. It also is officially the consumer version but carries only 5 years of fixes contradicting the 10 years fixes that Windows Enterprise carries.
