Today, the pool of available IPv4 addresses is close to being exhausted. As a result, enterprises need to move to an IPv6 infrastructure in order to maintain and scale their operations. The increased deployment of IPv6-based applications and services such as Windows Server is helping speed up this adoption. While it is imperative for enterprises to migrate to an IPv6 network infrastructure, it is important that the network also simultaneously support IPv4 to ensure a smooth transition and minimize capital expenditures and business disruption. In addition, the services available in an IPv6 network should be equivalent to or better than those available in an IPv4 network.
