IPv6
Companies world-wide start to embrace the new standard for communication
on the internet; the Internet Protocol version 6 - also known as IPv6.
IPv6 will at some point replace existing IPv4 which have been used to
transport our data through the internet for more than 30 years.
The main reason to switch is that IPv4 only allows around 4 billion
internet addresses. In order for one device to communicate with another
on the internet each of them has to have a unique internet address (IP
address). With the number of devices currently on the market -
computers, smartphones, smart tvs and set-top boxes - we are already out
of addresses. However, clever manipulation allows some devices to share
IP addresses with other devices, but this is not an ideal situation.
The sharing of addresses makes it difficult for devices to communicate
freely on the internet, thus limited functionality.
IPv6 solves the IP address issue simply by introducing a new type of IP
address that can handle 3.4e+38 - or 4 billion times 4 billion times 4
billion times 4 billion. It a huge number - difficult for most people to
understand. But lets just assume that we will not be running out of IP
address ever again.
Today (6/6/12) was been chosen by the
Internet Society to mark the launch of IPv6
. IPv6 has been around for many years but the deployment very limited -
and mainly used for research within companies and institutions. ISP,
hosting providers and other companies on the internet have been
repluctant to start offering services on IPv6, primarily because of the
investment required both in hardware, software and training.
The Internet Society on the other hand has tried to initiate a movement
encouraging ISP, webiste and hardware vendors to take the leap to IPv6
anyway - and thus promote their businesses by using cutting-edge
technology.
Another reason why IPv6 has taken such a long time to be accepted is
that it is not compatible with IPv4, even though they can exist side by
side. But not being compatible means that every piece of software
communicating on the internet has to be re-written to support IPv6.
Luckily, a lot of software already supports IPv6 - and especially open
source software. The communities around each of the open source projects
have a natural interest to support new features; and many projects
strive to be forerunners in these areas.
On Open Source for Free we have tagged each open source project that
supports IPv6 with an IPv6 tag - making it easy to see and search for
software that supports IPv6. A list of all IPv6 enabled open source
projects is available here:
Open Source with IPv6 support
One of the most important projects is
Apache
- the open source web server that hosts almost 2/3 of all websites on
the internet. Apache is also the web server used by Open Source
Alternative to make our website available on both IPv4 and IPv6. The
software, however, gets you nowhere, unless your hosting provider also
supports IPv6, which is the reason why Osalt switched toLinode VPS for great hosting and IPv6 connectivity to the internet.
On the other end of a connection to an IPv6 webserver is of course an
IPv6 web browser. Again, the open source community has the answer in
terms of
Firefox and
Google Chrome.
