Looking into the future of the internet – what will IPv6 hold?

By Tim Rooney, Director, Project Management Team at BT Diamond IP

Any scepticism surrounding the exponential growth predictions for IPv6 can be dismissed thanks to new data. Google statistics now show that the number of IPv6 users accessing its websites has now exceeded four per cent of total users, up from three per cent in February 2014. And this growth is expected to continue to reach between 9.9 and 14.9 per cent by the end of 2015.

With Google well known as the web’s favourite, this data gives a hint of trends that are happening all over the internet, offering insight into the future rise of IPv6 more broadly. With this interesting information available, I have used the data to create a projection that predicts the further growth of IPv6. [Read more…]

IPv6 block allocation made easy

By Tim Rooney, Director, Project Management Team at BT Diamond IP

Developing an IPv6 address plan can seem like nothing more than a massive headache. Such a plan defines how you intend to allocate subnets from the IPv6 block you received from your ISP or Internet Registry — it’s important stuff. It’s the kind of thing you need to ensure is done correctly.

The first step is defining how much address space is required across your IP network to give you an idea of IPv6 address capacity for those devices requiring it. You can use your current IPv4 address allocation database as a guide to define the active utilisation of your IPv4 address space and should provide a solid basis for IPv6 capacity needs, barring new network initiatives that increase address space usage. Once you’ve defined where in your network you require IPv6 addresses and how much is needed, you need to then consider how to perform your allocations. [Read more…]

Business agility: elasticity as the driver of cloud deployment

An increasing need for higher business agility remains one of the key drivers in the growing interest regarding cloud services. As each year, cloud computing ranks of the ‘technology prediction lists’. However, each year the tone continues to change as well, with less ‘cloud vapor’ and more focus on ‘business’. According to Forrester’s Craig LeClair, infrastructure elasticity should be seen as an enabler for other dimensions that make the business more agile and higher performing.

Whether you take a look at the evolutions in business domains such as information management, enterprise collaboration and work or at the fast digitalization across specific verticals, cloud computing is ranked as a crucial factor. The end goal of those evolutions, in many cases, is one of higher agility, at the same time one of the original drivers of the cloud to start with. This is not a coincidence in an increasingly real-time economy where business agility drives better business performance.

While agility and the ability to respond faster (and soon to pro-spond) to changing business, customer and worker demands is obviously not just a technology question, technology is an enabler of it. When looking at some of the IT and CIO priorities for 2014 as mentioned in a previous blog post (and many of us know this but can we turn it into action?), business is driving IT with challenging consequences. The same goes for business agility and cloud computing. [Read more…]

Twelve checklist items for deploying IPv6

Deploying IPv6 requires thorough consideration of your networking environment. As you can imagine, introducing a new network layer protocol has wide-ranging impacts. For example, if you constrain the initial scope of your deployment to your internet-facing infrastructure, you can better control the effort and expense required to deploy IPv6. You can also gain valuable IPv6 experience prior to a broader deployment involving your end-user community and associated impacts.

But for whatever scope you choose to define your IPv6 deployment, the following 12 points need to be examined and analysed to determine your readiness and potential upgrade requirements prior to implementation:

  1. IP infrastructure. Every major switch and router vendor has included IPv6 support for a few years now. As long as you’ve kept reasonably up-to-date with product releases, your switching and routing infrastructure should already support IPv6. It’s a good idea to validate this with your vendors, especially if you are relying on particular IPv6 features, e.g. mobile IPv6, etc. [Read more…]
