RIPE-631: IPv6 Troubleshooting for Residential ISP Helpdesks

We hope anyone deploying IPv6, and consequently staffing a help desk,
to find this document useful. Please feel free to borrow and adapt it
for your organization's needs.

I'm sharing it here on NANOG because this document is not RIPE region specific.

Disclaimer: this documents the use of -
which I'm perhaps a bit biased about. That said, the bulk of the body
of this work is coming from the community at large.
