Presentation_ID Value in caution Allows others to work through early inconsistencies Allows extended development and testing time for custom applications Allows normal life-cycle replacements to establish a capability baseline before turning IPv6 on

Presentation_ID Value in transition tools Primary approach of dual-stack enables independent deployment of applications in line with local business need Tunneling tools decouple decisions about application & end system deployment from infrastructure deployment Transition tools allow timing upgrades as part of a normal life-cycle plan, or to optimize investments
