Yep, and that's the only reason I'm trying to correct some apparent
misconceptions :-)

You're right, apparently the term is used by some cut-rate hosting
companies. You may have more experience -- I've only been running
web servers since 1994, and I've always used dedicated servers.

I didn't imply anything. I said they might be the same or they might
not. Either way, the IPs tell you which machines to examine.

One more confused paragraph. IP addresses are not "redirected";
HTTP requests are. And yes, the HTTP RFC specifies a number of
30x response codes, not just 301 or 302.

And I was trying to make the point that there's no need to "assume"
anything. Find the systems in question and check them directly. Or
at least that's what I'd do. YMMV.
