We understand the importance of the IPv4 shortage. If you are unaware of what's happening here is a quick rundown:

When the internet was first setup, an IP (internet protocol) address was designed to identify each machine connected to the network. The IP was designed as a 32-bit decimal number consisting of 4 groupings of 8-bits. For example, you may have seen a number such as 199.119.180.123. Numbers range from 0.0.0.1 up to 255.255.255.254. This gives approximately 4 Billion available addresses. Unfortunately, with the proliferation of technology, these numbers just didn't do the trick anymore.

Prior to the new Millennium, work began on a new numbering system. The old numbering system (above) was named IPv4 while the new version was called IPv6. The new numbering system is a hexadecimal system combining letters and numbers and is grouped into 8 groups of 16-bits, which looks like 2607:fd10:0001:0002:0000:0000:0000:0002. Because these numbers are so long, the leading zeroes and zero groupings can be shortened to make the IPv6 address a little more readable. A shortened version of the previous example would be 2607:fd10:1:2::2. The new system is a 128-bit system, greatly increasing the number of available addresses. The new addressing system consists of around 340 trillion trillion trillion addresses. Enough for every person on this planet to have 48,611 trillion trillion addresses each.

With this in mind, we set out to ensure that we were completely compatible with IPv6 from the get-go. Every client signing up with hosting packages can be assured that they will have their own IPv6 address assigned to their account. Setup is a little more involved than without IPv6 and currently the control panel software doesn't fully understand the new system. However, after some testing along with some trial and error, we have gotten it working so that IPv4 and IPv6 work side by side (dual stacked). cPanel should be fully compatible, according to their timetable, by the end of the year. When that time comes, automation will be implemented to ensure compliance with the new standards.

Further information about the IPv4 shortage can be found using Google or your favourite search engine. Keywords such as "IPv4 Shortage" should get you lots of results. We hope this information has been helpful and we look forward to earning your business!
