IPv4 address depletion dates have passed. We are handing out the last of our /8’s across our regional internet registrars now. In the near future we should be almost completely depleted of IPv4. This is concerning. What is more concerning is that SDN is gaining more traction than IPv6 deployment.

SDN, NFV and the surrounding technologies which aid in orchestration, abstractions, and automation. They improve and make easier the ability for businesses to achieve agility and consume compute to meet their requirements. SDN and NFV improve existing processes. They reduce costs in place as it is. From a business perspective, SDN is a resource, enablement, and profit optimisation technology.

IPv6 address adoption presents a pathway. It is a pathway to business continuity. When the appetite for consumption exceeds the remaining IPv4 addresses the ability to use internet resources will plateau. New business function is crippled. IPv6 deployment and adoption must increase. The industry needs IPv6 to be ubiquitous for business continuity.

Currently cloud providers offer elastic networks, scale, and massive compute consumption. The problem is many run across IPv4. Sure, some have a IPv6 overlay but not many have IPv6 native. When IPv4 runs out these networks will be severely crippled. Elasticity is not IPv4. Kludges will need to be employed or business function will be lost. Quite simply, IPv6 should be the foundation of all new deployments. This should already been done.

So with SDN full steam ahead, Juniper, Nuage, Cisco and many others are now executing strategies that play well in the SDN space, why is IPv6 being left behind? The future of the Internet is IPv6 and the future of the DC is SDN. Networking companies are addressing the scalability within the DC but the sad fact is the potential scale is crippled by running IPv4. Lets get focused guys. The growth of IPv6 means the growth of the internet, the increased consumption of cloud applications, and online business as a whole will cease. Let’s attempt to fix this.

  1. Very well spotted. ONF and IPv6 Forum are discussing the cooperation on this. The same is happening with the Openstack Foundation.

  2. I attended and spoke at the Australian IPv6 forum several years in a row, and eventually I got talking to the same people about the same things.

    I decided to just go out and *do it*

    1. Go out and do it. I like that mentality. I agree with your statement that it is always the same people. How do you suggest you broach topics with new people? The industry as a whole needs to lift their head up and step back. Only then can we see what is required.

  3. > Elasticity is not IPv4.

    Exactly. Private address ranges, endless IPv4 private subnet sprawl, ARP storms, NAT, DNS hacks, conflicting addresses on B2B tunnels, broken end to end voice and video.

    And SDN is propagating the mess.
