Planning IPv6 Deployment
From ARIN IPv6 Wiki
This RIPE presentation covers the highlights IPv6 Tutorial.
Google has a number of videos of Google tech talks on Youtube such as Google IPv6 Conference 2008: Planning for the IPv6 Integration.
There is a good blog on deploying IPv6 by the authors of O'Reilly's book on IPv6 Network Administration. Following this you get a good sense of the kinds of corner cases that you will need to deal with.
In addition to planning the IPv6 transport network deployment, you also need to consider DNS and Naming Issues carefully. DNS servers will send AAAA records to hosts which may have IPv6 capability on the host, but not on their access network. For many years, Apple Macs, Linux Machines and Solaris servers have supported IPv6 out of the box. If they try to use the IPv6 addresses that you advertise, but their access network does not support IPv6, your site will appear to be malfunctioning.
You need to collect a knowledgebase of how to Troubleshoot IPv6 Issues so that your helpdesk staff and your NOC staff are prepared for the inevitable queries that will come in.
In addition to your own needs for IPv6 Firewalls, you should prepare to help customers with information about new IPv6 firewall vendors as the market changes.
It is important to look at the different transition mechanisms and understand how and why you can implement these in your network to improve service to customers during the transition period when many Internet flows will have to travel over both IPv4 and IPv6.
- Transitioning: 6to4
- Transitioning: NAT64
- Transitioning: NAT-PT
- Transitioning: Teredo
- Transitioning: Tunnel Broker
There is more info on the Relay Services page.
You should also evaluate IPv6 Firewalls both for your own use and to recommend to customers.
