获取短域名的whois数据

Question

Let say, we want to get a date of registration of a domain name. This information can be easily obtained from whois.crsnic.net server (on port 43). However, if we want to obtain that kind of information for a short domain like AAA.COM, chances are, the server will respond like this:

Whois Server Version 2.0 Domain names in the .com and .net domains can now be registered with many different competing registrars. Go to http://www.internic.net for detailed information. AAA.COM.CN AAA.COM.TW AAA.COM2.CN AAA.COM To single out one record, look it up with "xxx", where xxx is one of the records displayed above. If the records are the same, look them up with "=xxx" to receive a full display for each record. ...

Obviously, it means that there are same domains with the same TLD base. How can I get the record for AAA.COM in this case? I dont really understand what does following mean.

To single out one record, look it up with "xxx", where xxx is one of the records displayed above.

Right now, my query looks like this

$sp = fsockopen ("whois.crsnic.net", 43);
fputs ($sp, "aaa.com
");

Answer 1

If you send =aaa.com, you'll get a response that includes the following:

This tells you that the appropriate whois server for aaa.com is whois.networksolutions.com. So you should retry using that server, and you'll get the details:
