This is really the topic of this entire book. In the long term, we expect that "running an IPv6 network" will be synonymous with "running a network". IPv6 should not be viewed as an add-on, but as the primary network protocol. How it coexists and interacts with IPv4 is the subject of Chapter 3. This section gives an overview of how IPv6 looks when viewed from the NOC, and the rest of the book covers the details.
IPv6 is at its roots not fundamentally different from IPv4 - just different in almost every detail. So the nature of NOC design and operation is not changed by IPv6, but existing operations and management tools need to be updated. For example, any configuration databases, whether home-grown or purchased, must be able to handle IPv6. For operators, there are many new details to learn. Also, supporting IPv4 and IPv6 simultaneously is obviously more complicated than supporting only one protocol.
Enterprise networks, carrier networks, and data center networks each have their own requirements and challenges, with differing geographical spreads, availability requirements, etc. Various chapters of this book tackle different aspects of NOC operations: 5. Network Design, 6. Management and Operations, 9. Troubleshooting. The 7. Case Studies will also be relevant to NOCs.
