It does not have to resolve to an IP address at all. It only has to have an SOA record and an NS record (preferably more than one); and not even that, if it is a subdomain that is not a separate zone.<br><br>(2)
There is no requirement that a domain name refer to the Web site for that domain. I personally don't like that (for no special reason), and neither apparently does the owner of this domain, who forces people to go to the trouble of typing in www.p3net.net to get to his or her Web site. Incidentally, there is no requirement that the domain name refer to a mail server, either (which used to be common before the Web existed), or to an FTP server, or to a Telnet server, or to a nuclear reactor control device. Or to anything.<br><br>(3) However, any name MAY resolve to any IP address, routable or not. That doesn't mean there's anything useful, or even related to that domain, at that IP address.<br><br>(4) "127.0.0.1" is the IP equivalent of the English language word "me". If I say, "me", I am referring to myself. If you say, "me", you are referring to yourself. It cannot be used to direct anyone to somewhere else. In
fact, some use it to deflect probers AWAY from themselves, and back on the prober's own server. (E.g., if I wanted to probe "p3net.net", my server would be probing itself!)<br><br>(5) 127.0.0.1 is not among the IP addresses mislabeled as "unroutable". It is always routable. To right here. Well, for you, right there.<br><br>(6) Just because OS X has 127.0.0.1 as the resolver has no effect on what that resolver returns. Don't confuse the concepts.<br><br>I think there were some others, but it's getting late.<br><br>Joe Yao<br>_______________________________________________<br>Please visit <a href="https://lists.isc.org/mailman/listinfo/bind-users" target="_blank">https://lists.isc.org/mailman/listinfo/bind-users</a> to unsubscribe from this list<br><br>bind-users mailing list<br><a ymailto="mailto:bind-users@lists.isc.org" href="mailto:bind-users@lists.isc.org">bind-users@lists.isc.org</a><br><a
