IPv6 Transition Strategies
As we reach the end of the supply of IPv4 addresses, networks need a strategy to deal with the coming changes. Part of that involves adapting network architectures to support IPv6. But there's more.
IPv4 isn't going away completely any time soon. It's best to plan now, while addresses are still available, for IPv4 support into the future. IPv6 networks are not yet at IPv4 levels of reliability. An IPv6 plan needs to ensure that it improves services for users, rather than making service worse. Full support for IPv6 is still missing in some network equipment, so planning needs to include work arounds and purchasing strategies.
We've already been through this many times, and can help with all areas of your IPv6 strategy.
