At a time when IPv4 reserves are running scarce, IPv6 is the only way out. IPv4 reserves dropped to 5% in October 2010 and it has been more than a year since then. Clearly, many companies are already using IPv6 and as it seems, they are ready for the transition to IPv6. A number of Internet-giants gave IPv6 a trial on June 8 last year too, which helped them test their networks with IPv6 and gain some valuable insight.
We will know soon when Akamai, Facebook, Google and Yahoo will participate in the first global trial of IPv6 on June 8. With their distributed servers spread all over the world, these companies will form the ideal testing ground and will churn up some useful real-time data.
Following last year’s experiment, this year they are planning a World IPv6 day on June 6. However, they will not return to using IPv4 as they did last time this experiment was performed. Clearly, this is not a test; it is a transition. World IPv6 launch is being promoted through a website- World IPv6 Launch, which lists out all the participants and a link to their IPv6 page.
There are over 250 participants in this transition, majority of them being large website operators. Big brands like Cisco, Google (has already deployed IPv6 internally), Microsoft, Yahoo, Comcast, AT&T, Free, Time Warner Cable and D-Link are among the participants of this mega event, and it will be a turning point in the history of Internet. However, the participants in which you should take special interest are the ISPs, namely Comcast, Free Telecom, Time Warner Cable, AT&T, Free Telecom and Internode. At the end of the day, they are the ones serving Internet connections to every household in the nation.
Google has always been enthusiastic about the new Internet protocol IPv6, and was one of the few companies to try IPv6 on the World IPv6 Day, in January this year. The trial run gave Google some valuable insight into IPv6, and almost after a year, Google has revealed that 95% of its network has been transitioned to IPv6 successfully.
Google’s Network Engineer Irena Nikolova discussed the implementation of IPv6 at Google, at the Large Installation System Administration (LISA) Conference this month. As IT World puts it,
Google has learned that an IPv6 migration involves more than just updating the software and hardware. It also requires buy-in from management and staff, particularly administrators who already are juggling too many tasks. Moreover, for early adopters, it requires a lot of work with vendors to get them to fix buggy and still-unfinished code.
Google’s migration to IPv6 started as a 20% project in 2008, and after four years, their goal of “IPv6 everywhere”‘ seems close. Google also devised a mechanism that allows connecting devices to acquire IP addresses, even if their operating systems do not support DHCPv6 (the IPv6 counterpart of DHCP). In addition to this, they have also developed their own address-space schemes.
This paper accompanying the presentation gives more details.
Tech giants are midway through switching to IPv6 and it is getting some fair attention at the same time. Network World is holding a conference on IPv6 today, called “The Critical Path to IPv6“. This conference will explain why IPv6 is important for your organization, and why you should gear up for it. Very soon, IPv6 will breathe life into the dying IPv4 address-space.
IPv4 is a thing of the past as of this month. The IP address reserve for IPv4 dropped to 5% in October last year and the sudden increase in the number of mobile devices and the increasing awareness towards using the Internet has exponentially increased the number of connected computers all over the world. The result- an IP adddress fiasco.
The only savior in this situation is IPv6 and we all are turning to it. Google has decided to try out IPv6 with Facebook, Akamai and other major players on the Internet. The transition from IPv4 to IPv6 is a tedious job. The existing routers do not have all capabilities for this and now that it is more of a compulsion than an option, any further network changes will incur a huge cost for organizations.
Even more worrying, is the fact that current implementations of IPv6, which amount to less than 1% of the total Internet hosts is quite imperfect. On the 8th of June, Google, Facebook and Akamai will generate some interesting statistics on the usage of IPv6 that will lay the foundation for usage of this new protocol.
2010 is the last year for IPv4 and this has been foreseen as early as March 2010. However, the transition from IPv4 to IPv6 is a huge concern for the Internet at large because IPv6 has a different packet format and is not interoperable with IPv4. However, IPv6 makes use of routers more efficiently as compared to IPv4 and this will reduce the computational load from routers.
IPv6 will provide an intelligent mechanism for calculating the minimum size of data that can be transmitted between two end-points (read PMTUD). In short, the routers will speed up but the network cables will slow down.
The result of this transition is unknown though in theory, it should make effective use of the hardware. We will know soon when Akamai, Facebook, Google and Yahoo will participate in the first global trial of IPv6 on June 8. With their distributed servers spread all over the world, these companies will form the ideal testing ground and will churn up some useful real-time data.
IPv4 has been in use for three decades now and the test on 8th June will be a Game-Changing event.
Techie Buzz readers are probably already aware that we are running out of IPv4 (Internet Protocol version 4) addresses. An IP address is essential for uniquely identifying devices connected to the internet. The trouble is that the currently prevalent protocol (IPv4) only supports up to 232 addresses, which was thought to be enough back in the day. With the number of devices connected to the internet rapidly increasing, we are quickly nearing the exhaustion of the address pool.
A newer version of the protocol – IPv6, solves this problem, while introducing other significant benefits. IPv6 supports 2128 (about 3.4Ã—1038) addresses. Unfortunately, IPv6 protocol requires new hardware or updates to legacy hardware. However, users on IPv6 networks will still be able to access content on IPv4 networks. In spite of the repeated efforts, the adaption rate of IPv6 has been slow due to the financial investments required and general consumer apathy.
The Number Resource Organization (NRO) has announced that less than 5% of the addresses now remain unallocated. The good news is that IPv6 adoption increased this year by 70% compared to just 8% for IPv4. This indicates that IPv6 adoption is gaining momentum. On its part, the Indian government requires all telecom and ISPs are required to be IPv6-compliant by the end of next year, and wants to start using IPv6 by March, 2012. However, unless the ISPs get their act together, even this might turn out to be too little too late.
Like many other countries in the world, India too is running out of IP addresses on IPv4. This problem of IP address crunch is likely to get more fierce with the upcoming rollout of 3G and broadband wireless access (BWA) services in the country.Well, we as Internet users need not worry at all. According to a new roadmap released by the Indian government, India will start using IPv6 (Internet Protocol version 6) – a technology that offers more IP address space than what IPv4 provides currently, from March 2012.
All telecom and ISPs are required to be IPv6-compliant by the end of next year and offer IPv6 services thereafter, the government said in a statement issued on Wednesday by the country’s Press Information Bureau. The switching process will start with Federal and state government ministries and departments and public sector companies who will adopt these new IPv6 services by March 2012.
The IETF is holding its 77th meeting this week at Anaheim, California. The last meeting saw a huge turnout and the IEFT grabbed this opportunity to promote the new IP protocol, the IPv6.
The IETF as described by Wikipedia is,
The Internet Engineering Task Force (IETF) develops and promotes Internet standards, cooperating closely with the W3C and ISO/IEC standards bodies and dealing in particular with standards of the TCP/IP and Internet protocol suite. It is an open standards organization, with no formal membership or membership requirements.
This Tuesday, researches have shown that even in small numbers, Internet users are already adapting to the 1995 technology. ï»¿Geoff Huston of APNIC has recently announced from traffic data in the Asia Pacific that at least 1% of the Internet is using IPv6. Though not much, this is surely a good start. APNIC is the Regional Internet Registry for the Asia Pacific region.
The data provided by Huston is significantly important. It has revealed interesting facts like:
If IPv6 is implemented, it will not affect the ISPs. Current IPv4 requires them to send a data in multiple parts of small size and IPv6 requires them to send one huge data at a time. The effective change is minimal.
Around 6% of all networks have IPv6 enabled routers and at the current growth rates, this number will increase to 80%.
Comcast had once announced an IPv6 trial and more than 5000 people even changed their ISPs to be able to avail this offer. This shows that people are enthusiastic about IPv6. It is the existing network infrastructure which is reluctant to make this change.
