Why are you even worrying about that? Use DNS.

I haven't checked yet if my external dyn dns accepts IPv6. If they do, then I'll have to modify the scripts, which will take some time.

For a quick test, which was all I was trying to do, I need to enter the IP address into firefox.

And I wanted to do the test forcing FF to use IPv6.

I have been using IPv6 for close to 13 years and almost never use the IPv6 address. If you don't have DNS available, use the hosts file.
