There is no such translation.  Rather, there used to be, but it has been
deprecated (that is, it's not supposed to be used any more).

IPv6 and IPv4 are essentially two separate networks running on the same
wires.  To reach your Web site via IPv6, your Web site must HAVE IPv6
installed, must have an IPv6 IP address, and must have a way of getting
IPv6 from your site out to a fully connected IPv6 router at your ISP.
Any IPv4-only router in the way will completely block the IPv6 flow.

Also, IPv6 must be understood all the way up to the applications level.
This should not be a problem with Apache's 'httpd' Web server, as long
as you put in either a "*" IP address or both the Web server's IPv4 and
IPv6 IP addresses.  I don't know about other Web servers; I know some
are not IPv6-aware.

Oh - you can't make up an IPv6 address; you have to use one that is
compatible with the IPv6 transport you get.
