The IPv4-compatible IPv6 address is indeed deprecated, but there is a non-deprecated method; the IPv4-mapped IPv6 address (section 2.5.5.2 in RFC 4291): :::a.b.c.d where a.b.c.d are the four octets, represented in decimal, of an IPv4 address. However, this just allows an ordinary IPv4 address to be "packaged" in an IPv6 address. An application that understands this format will just extract the IPv4 address and use it *as an IPv4 address*. It's not a "transformation" in the sense that the OP seems to want.

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. -- /*\ ** ** Joe Yao j...@tux.org - Joseph S. D.
