It is possible that the server at the literal address uses the virtual name
to serve the page from that address. I do so in an IPv6 enabled cloud
machine. Since the name I wanted served is by a server that serves several
sites depending on the name, trying to do what you asked resulted in me
getting the default page per my server config. Now I'll go back and add
the literal address as a separate virtual name. Thanks for bringing my
config error to my attention as I had intended that server to serve it and
had only put up the dns entry to tell it to go there. Others may have done
so also and if so, you'd get their default page.

And another fail. It appears my cloud will not allow me to add a literal
address to my server so maybe it doesn't/won't work. It doesn't really
bother me as I don't think my intended visitors even know what an IP
address (v4 or V6) is! And that one that does will just call me.

Thanks!

Thus wrote Schmoll, Carsten (carsten.schmoll@fokus.fraunhofer.de):

> * IPv4-only client in IPv4-only subnet running a web browser

If the client was of an ancient enough software that didn't know what IPv6
was (in contrast to a client that knows IPv6 but merely doesn't have it
active), you would get a syntax error (no []: allowed in hostnames).
