    • In order to access a web site, for example one identified by a domain name, a client device must determine the network location, or IP address, of the webs site. In one example, the corresponding IP address of the domain name has been stored locally at the client device but has expired. The client device may send a request to network location of the expired IP address while concurrently sending a request to a domain name server for updated IP address information. If the updated IP address received from the server is the same as the expired IP address, the client device may request the web site information from the previously established connection. If the updated IP address is not the same as the expired IP address, the client device may abort the connection with the expired IP address and establish a new connection with the updated IP address.
    • 为了访问网站,例如由域名标识的网站,客户端设备必须确定网站的网络位置或IP地址。 在一个示例中,域名的相应IP地址已经存储在客户端设备本地,但已过期。 客户端设备可以向已到期的IP地址的网络位置发送请求,同时向域名服务器发送更新的IP地址信息的请求。 如果从服务器接收到的更新的IP地址与过期的IP地址相同,则客户端设备可以从先前建立的连接请求网站信息。 如果更新的IP地址与过期的IP地址不同,则客户端设备可以中止与过期的IP地址的连接,并与更新的IP地址建立新的连接。
