Question

假设我们希望获得域名注册日期。可以从whois.crsnic.net服务器（在端口43上）轻松获取此信息。但是，如果我们想获得像AAA.COM这样的短域的那种信息，服务器可能会这样回复：

Whois Server Version 2.0 .com和.net域中的域名可以现在注册了许多不同的竞争注册商。去 http://www.internic.net了解详细信息。 AAA.COM.CN AAA.COM.TW AAA.COM2.CN AAA.COM要挑出一条记录，请查阅使用＆＃34; xxx＆＃34;，其中xxx是上面显示的记录之一。如果记录是相同的，用＆＃34; = xxx＆＃34;查找它们。收到一个完整的显示每条记录。 ...

显然，这意味着存在具有相同TLD基础的相同域。在这种情况下如何获得AAA.COM的记录？我真的不明白以下是什么意思。

要挑出一条记录，请查找使用＆＃34; xxx＆＃34;，其中xxx是上面显示的记录之一。

现在，我的查询看起来像这样

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

Answer 1

如果您发送=aaa.com，则会收到包含以下内容的回复：

这告诉您aaa.com的相应whois服务器是whois.networksolutions.com。因此，您应该重试使用该服务器，并且您将获得详细信息：
