But if you didn't know that fact, you might want to invest in a proper book about IPv6 and read up quite a bit. As this is NANOG, a good operational book is "Running IPv6".Thank you for the book recommendation; however, I was trying to get an admission that any IPv6-connected end users or corporate connections, will be accessing IPv4-only resources for a long time to come, i.e. years and years. And that the responsibility for IPv6 to v4 connection won't have to be handled by my client with a few racks.
Noone can confirm that for you because it is largely untrue. IPv6-connected end users MAY have some ability to reach your IPv4-only site. This will be through something that looks like a LSN device at best so you won't have working things like: Geolocation UPNP reverse connection mapping Most forms of NAT-T Most forms of P2P Logs that represent unique IP addresses visiting your site in a meaningful manner. etc. Owen
