Due to the number of limited number of internet addresses, a new internet protocol has come available to consumers, IPV6. “Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that routes traffic across the Internet. It is intended to replace IPv4, which still carries the vast majority of Internet traffic as of 2013” (IPv6, 2013). The Internet has experienced an astonishing increase of devices accessing the Internet. Because of this increase, IPv4 addresses are running out.
The solution is for IPv6 to accommodate this increased demand by providing a much larger address space, along with improved traffic routing and better security. There are several advantages and disadvantages with IPv6. Some advantages are: IPv6 provides more address space, which is being needed in larger business scales, such as: Comcast. It is a more powerful internet (128bit versus IPv4’s current 32 bit). It offers and overall larger scale internet, which again will be needed in the future. Address allocation is done by the device itself and support for security using (IPsec) Internet Protocol Security.
IPv6 includes plug and play, which is easier for novice users to connect their machines to the network. Essentially, configuration will happen automatically. Some disadvantages are: It will be much harder to remember IP addresses (compared to the addresses now). It is not easy creating a smooth transition from IPv4 to IPv6. IPv6 is not available to machines that run IPv4. The cost in having to replace an IPv4 machine and the time to needed to convert over to IPv6. It is not so widely used by residential internet service providers. (IPv6 Advantages and Disadvantages 2012) What was World IPv6 Day? On June 8, 2011, The Internet Society (ISOC) sponsored a 24-hour global test of IPv6. Major organizations such as content providers and web, networking, and software companies enabled IPv6 on their main websites for 24 hours” (World IPv6 Day, n. d. ). This event was known as “World IPv6 Day”. The goal of the Test Drive Day was to motivate organizations across industries, such as: Internet service providers (ISP), hardware makers, operating system vendors and web companies, in order to prepare their services for IPv6 and to ensure a successful transition as IPv4 addresses run out.
Where do things currently stand? As with all technology, IPv6 gets better and cheaper over time. Just like with buying a car, people prefer waiting rather than buying when prices are high. To make matters worse, if you’re the only one adopting IPv6, this buys you very little. You can only use the new protocol once the people you communicate with have upgraded as well. Worse still, you can’t get rid of IPv4 until everyone you communicate with has adopted IPv6.
So some people want to move to IPv6 and leave IPv4 behind sooner rather than later, but others plan on sticking with IPv4 until the bitter end. Some reasons why companies have not switched to Ipv6 are: The Company is too cheap, and IPv6 is not cheap. Some organizations believe that Ipv6 is not secure enough yet. Potential security issues with IPv6 have happened. For example, IPv6 could be turned on, and because of tunneling and network address translation (NAT), someone could be using IPv6 on your network without your knowledge.
