I'm considering the possibility of moving my public addresses to IPv6 for several web applications and sites that I host.
When inquiring with my ISP, the account exec replied to me with the following warning:
"I was checking in with the Engineer that is working on IPv6’s and he just sent me the following: Do they realize that if we give them IPv6 addresses they are, generally, only reachable from other IPv6 hosts?"
I'm not sure if I understand what is being referred to here. My public DNS provider has verified that their DNS services are fully v6 compliant and as long as my own equipment is capable, why would the ISP issue such a warning to me?
