IPv6: The future of net addresses explained
Why it'll make things easier but won't solve security issues
Why is there so much fuss about IPv6 at the moment? Why do we need it, and what's it for?
The answers are becoming increasingly important as the pool of IPv4 addresses finally begins to run out.
By this time next year the drought will begin to bite – or so it's reckoned – but will IPv6 solve any of the problems and exploits currently made possible by IPv4?

AT&T sees businesses wading slowly into IPv6
Even though we're due to run out of IPv4 addresses in the next year, AT&T doesn't expect enterprises to be fully IPv6-ready when D-Day arrives.
The biggest hurdle for a lot of customers is simply understanding the scope of what has to be done to migrate to IPv6," says Dale McHenry, the vice president of enterprise networking for AT&T Business Solutions. "There's just a lot of parts. It's amazing how broad IP addressing is with all the sub-networks that are active in our own internal systems."

How To Deploy IPv6 In Your Organisation
The Internet is running out of the current version of IP addresses. Maintain competitive advantage and save money by switching to IPv6 now
From its humble beginnings a few decades ago, the Internet has experienced explosive growth due to the rise in personal computers as well as other connected devices such as mobile phones and gaming consoles. It forms an integral part of our daily lives and many of us can no longer imagine a world without email, search and online shopping.

The advantages and disadvantages of IPv6
pv6 is considered the future successor of the old internet protocol, Ipv4. Although Ipv6 has began serving in the current time, Ipv4 is still the main controller of the market. Yet, Ipv4 is suffering from a serious exhaustion and problems which are giving focus to the upcoming Ipv6.
Both Ipv6 and Ipv4 are Internet protocols for addresses. This means that each of them is a numerical system which allows each computer connected to the internet to be recognized by a specific IP address. This is an essential role for the internet since computers communicate using numbers rather than names. Yet, humans have developed the DNS (domain name system) to solve the problems associated with interacting with the Internet Protocols. In fact, domain names are simply alpha-numerical combinations stored in specific servers and each pointing to a specific IP address.

Microsoft’s Tech.Ed goes IPv6
Microsoft’s annual event for IT professionals, Tech.Ed, will this year deploy IPv6 (Internet Protocol version 6) for the first time in an effort to drive education and awareness about the technology.
Microsoft Australia’s Web platform evangelist, Jorke Odolphi, said whole industries were currently viewing IPv6 as “a bit too hard” and were unsure of how the next generation protocol worked.
“There’s been a lot of talk about IPv4 being depleted and reached exhaustion, saying the internet is getting full and that’s one way of thinking about it,” Odolphi said.
“I believe the problem comes down to application developers and people who are running software that has hard coded tendencies on IPv4. When we actually start to run into these problems, there’s going to be a whole bunch of applications that need to be updated and that’s going to be a big challenge for IT in Australia and developers.”

IPv6 Deployed But in Unexpected Places
Eric Vyncke reporting in the NetworkWorld: "IPv6 exists for more than 15 years and it is rumored to be deployed extensively in Asia and especially in Japan and China with Africa being the last continent to deploy IPv6. Another place where there should be a lot of deployments is of course in the USA with the US Government IPv6 mandates. But, when it comes to measure where web sites are actually deployed over IPv6, the rumor proves to be just a myth..."

Free IPv4 and IPv6 DNS hosting
Hurricane Electric now offers free DNS hosting. This service provides both native IPv6 and IPv4 authorative nameservice, supports A, AAAA, CNAME, MX, NS, TXT, SRV, and PTR records, as well as IPv4 and IPv6 reverse zones.Hurricane Electric now offers free DNS hosting.

The Road To IPv6 Is Paved With NATs
Even though IPv6 adoption is dangerously slow, we will see adoption eventually. There are three main sections of the Internet that need to handle IPv6. The Internet networking equipment like routers, proxies and firewalls, and services like DNS and routing need to support IPv6 so that clients can talk to servers that users are connecting to from giants like Google and Amazon to smaller web, email and other hosts. Then, there are the enterprise and consumer products that will connect to Internet hosts. The question remains how to deliver IPv6 services in a non-disruptive manner to consumers in homes, small businesses and enterprises, all of whom can't control either the content being provided or the consumers visiting that content.
To this point, IPv6 adoption on the broader Internet remains in its infancy. The 2,500 IPv6 prefixes announced today on the Internet are a fraction of the 300,000 IPv4 announcements, says Earl Zmijewski, vice president and general manager at Renesys. What's more, most of these IPv6 announcements are run by research institutions, he says.

IPv4 Runs Low Faster Than IPv6 Is Adopted
According to engineers at Hurricane Electric and iNetcore, by mid September, 2011, the Internet registries are expected to run out of routable IP addresses to assign.
On the Seinfeld episode, "The Dealership," Kramer takes a test drive. The salesman asks about gas and Kramer responds, "There's still some overlap between the needle and the slash below the "E"...I've been in the slash many times. This is nothing. You'll get used to it."
We'll be approaching "the slash" soon enough as addresses for users, hosts and devices will suddenly become a scarce resource. While 2012 apocalyptic visions aren't expected, the problem remains serious. Migrating to IPv6 is the leading approach, with its much larger address space of a little more than 340 trillion addresses. IPv6 could also introduce a number of engineering headaches for enterprises and consumers.
