WHOIS（讀作Who is,，非縮寫）是用來查詢域名的IP及所有者等信息的傳輸協(xié)議。簡(jiǎn)單說,，WHOIS就是一個(gè)用來查詢域名是否已經(jīng)被注冊(cè),，以及已經(jīng)注冊(cè)域名的詳細(xì)信息的數(shù)據(jù)庫(kù)（如域名所有人、域名注冊(cè)商,、域名注冊(cè)日期和過期日期等）,。通過域名Whois服務(wù)器查詢，可以查詢域名歸屬者聯(lián)系方式,，以及注冊(cè)和到期時(shí)間,。本文介紹實(shí)施WHOIS信息查詢的方法。
1. WHOIS查詢網(wǎng)址
通過訪問網(wǎng)址http://whois.chinaz.com/,，可以快速地查詢到某域名的相關(guān)信息,。在瀏覽器的地址欄中輸入網(wǎng)址http://whois.chinaz.com/，訪問成功后,，顯示界面如圖1所示,。
圖1 Whois查詢站點(diǎn)
在如圖1所示的文本框中輸入要查詢的域名，并單擊“查詢”按鈕,，即可獲取到對(duì)應(yīng)的信息,。例如，查詢域名qq.com的相關(guān)信息,。查詢完成后,，顯示如圖2和圖3所示,。因?yàn)闊o法截取所有信息，所以這里只截取了兩個(gè)圖,。
圖2 域名信息
圖3 Whois查詢
在圖2中顯示了域名qq.com的信息,，包括該域名的注冊(cè)商、聯(lián)系郵箱,、電話,、創(chuàng)建時(shí)間、過期時(shí)間和域名服務(wù)器等,。
在圖3中顯示了域名qq.com的WHOIS信息,，包括注冊(cè)域名ID、注冊(cè)WHOIS服務(wù)器,、注冊(cè)的URL,、更新時(shí)間和創(chuàng)建時(shí)間等。
2. 使用Whois工具
