If so, then if IP address 111.222.333.444 is > foo.com, then > bar.com, then foo.com again, are foo.com and bar.com identical? But my questions remain: Is there ever a time when we need/want an application to know or think that foo.com is the same as bar.com? My understanding is that the DNS name is what we're after; the IP address is just how we get there. If we want our application to use foo.com then we will; if bar.com happens to be "the same" as foo.com, however you define "the same", does that matter to us at all? We can still go on happily using foo.com in our application, and bar.com can be the same, and then change, and we won't care. But I have another question, to add to the previous one: in the case of namespaces (is that where this thread started?), in the example you cite, is the second foo.com the same as the first foo.com? Wait, don't answer that, I want to go over the implications in my head for a bit first... I have a feeling it's going to be application-specific, and also have some legal ramifications. (I define foo.com. I go out of business, but someone else buys the foo.com name. e.g. ad infinitum) David Hunter david.hunter@m...
