Googlebot 及 Yahoo Crawl

*** 登錄論壇才可看到文章內的圖片 *** 我們在論壇以管理員身份去看 "在線用戶" 時，論壇會顯示訪問者的 IP 地址，有時我們會發現來遊客的數字一下子突然急升 (試過突然增加數十個)，再看一下IP 地址, 發現有一連串連續  IP 地址，例如我們試過看到 66.249.68.x 及 66.249.67.的多個來訪者，到我們論壇的不同帖子，好像在讀取資料，於是我們馬上利用Ping 去找一下這些IP 地址的來源， ping -a 66.249.68.69 發現 Host 為 crawl-66-249-68-69.googlebot.com，應該是google搜尋引擎的 googlebot 來讀取網頁資料。

Yahoo 也有，你 ping 一下 67.195.37.167 及 67.195.37.168 便找到了，host 名字叫 llf320042.crawl.yahoo.net  及  llf320043.crawl.yahoo.net

** crawl 解作 "爬行"，spider 是其中一種爬行的昆蟲
