下面的查詢顯示了大約10個屬於google.com的IP地址。那麼,這是否意味着只有10臺服務器作爲發送給谷歌的任何查詢的第一站? 即使這些僅用於負載平衡,它們如何處理數百萬個請求?負載平衡服務器負載爲google

 
host google.com 
google.com has address 74.125.228.32 
google.com has address 74.125.228.33 
google.com has address 74.125.228.34

看看這個:

bash-3.2$ host google.com 
google.com has address 212.188.10.114 
google.com has address 212.188.10.88 
google.com has address 212.188.10.98 
google.com has address 212.188.10.84 
google.com has address 212.188.10.93 
google.com has address 212.188.10.108 
google.com has address 212.188.10.99 
google.com has address 212.188.10.123 
google.com has address 212.188.10.109 
google.com has address 212.188.10.104 
google.com has address 212.188.10.119 
google.com has address 212.188.10.94 
google.com has address 212.188.10.118 
google.com has address 212.188.10.89 
google.com has address 212.188.10.103 
google.com has address 212.188.10.113 

換句話說,來自不同國家的用戶獲得不同的IP爲 'google.com'。所以至少有更多的IP地址,而不僅僅是10個左右。
