No longer if but when.
IPv6 deployments are becoming more widespread as organizations face the inevitable depletion of IPv4 address space. Seventy percent of survey respondents have deployed, are deploying or will deploy IPv6 within two years.
Growing acceptance of the need for IPv6.
Our 2015 IPv6 industry survey found that industry opinions about IPv6 are growing more accepting of the necessity and requirements for IPv6 and less questioning of the value and benefits provided. This is our fifth annual survey which followed two prior triennial editions, and results over the years indicate the industry has emerged from the state of denial and inquisitiveness to one of readiness and action.
While technical obstacles and business justification challenges remain, the near exhaustion of IPv4 address space at the second tier of the Internet’s addressing authorities has spurred many organization to act. The top tier, the Internet Assigned Numbers Authority, IANA, depleted its space in February, 2011. The second tier, comprised of Regional Internet Registries like ARIN, RIPE and APNIC, have now all but depleted their respective supplies of IPv4 addresses. As the Internet continues to expand, IPv6 addressing will by necessity become more prevalent.
Key survey findings include:
One-third of survey respondents indicated that they had already deployed IPv6 throughout all or a portion of their networks. Another twenty-three percent are actively deploying IPv6 and fifteen percent plan to deploy within two years.
IPv6 deployment propensity is directly proportional to network size, with ninety percent of operators of larger networks with over 100,000 IP addresses, actively deploying IPv6, if not already having completed deployment.
Service providers led deployments with ninety-four percent deploying or having deployed. Enterprises have also been busy with two-thirds of such respondents indicating IPv6 deployment activity.
Leading benefits of IPv6 deployment include continued global Internet presence as the Internet evolves from a homogenous IPv4 network to a dual protocol IPv4-IPv6 Internet. Other benefits included the potential for innovative applications and support for the Internet of Things (IoT).
The inability to demonstrate a clear business case was viewed as the leading obstacle, followed by the complexity of infrastructure upgrades and the conversion of existing applications and middleware.
