问题回答

http://www.google.com。

ARP用于从IP(1.2.3.4)获得MAC地址(11:22:33:44:55:66)。

请在您的浏览器上写www.google.com:

  1. It needs to find out what IP is www.google.com, so it uses DNS to do that.
  2. It needs to send packets to the IP address of www.google.com, but in the Ethernet level, this means you first need to send the packets to the next router in the route to the target (probably your default gateway).
  3. To do that in the Ethernet level, you need to know what is the MAC address of the default gateway - this is done using ARP.

ARP向局域网发送了问题——谁有1.2.3.4? 无论由谁来回答——因此,投稿人都知道,MAC地址是1.2.3.4,他需要将包装包寄给他。
