Hi All,

I'm assisting a group to write a best practice document and we're wondering what is the best practice on IPv6 PTR for subscribers and for enterprise?

- What are ISP doing in regards to responding to IPv6 PTR requests?
- Is not responding to PTR acceptable? When?
- What applications are requiring IPv6 PTR support?

Any feedback appreciated,
