IPv6 Network Administration

Worked Examples

In this section we present an overview of the deployment of IPv6 in some representative networks. We look at both the technical and organizational aspects of same. The first example we look at is that of an enterprise-class IPv4-connected network, the second a transit ISP, and the third—a special case—an Internet Exchange Point.

Enterprise-class IPv4-connected network

Step 1

XYZ Corp, a company owning its own network, decides to implement a pilot IPv6 program to provoke a thorough audit of their in-house applications, which recently demonstrated fragility in the face of network instability. The pilot IPv6 programme will establish the minimum necessary IPv6 connectivity to test the applications on the internal desktop and server networks. External IPv6 connectivity is not absolutely required but will be delivered if possible.

The development team are instructed that when they are going through the code-base for the company applications, they should alter the code to be address independent and to be more resilient to failures. The implementation team have to deliver a working IPv6 platform not for the development team, who are anticipated to take quite some time when reworking the code, but for the testing team, so there is ample time for the deployment to take place.

Step 2

The deployment team begin the communication process by running an internal IT staff course in IPv6; they might use this book, vendor materials, and so on. They set up a machine for the IT department ...
