With the depletion of IPv4 addresses, more organizations are encouraged to transition over to using IPv6 addresses. Many organizations are noticing the benefits of the built-in security features of IPv6. Also, enterprise IT managers are observing that their service providers are successfully using IPv6, and this encourages them to move forward with it.
To continue to ignore IPv6 could cause any number of potential problems, including an inability to immediately migrate to IPv6 when there is no longer a choice, loss of internet connectivity, and not being able to compete with organizations whose systems are configured for IPv6.
