A DNS server performs this translation function. In your system's TCP/IP configuration, one or more DNS servers are specified by their IP addresses, and these servers are queried when a domain name needs to be translated to an IP address. (Typically, one or more DNS servers will be configured for an ISP or corporate network; name service is usually centralized.)</p><p/><p>Since the <b>DNSServers</b> <control_st tag="function">function</control_st> reads the value set in the network configuration, it is available even if the system is not currently connected to the <keyword tag="internet">Internet</keyword>.</p>
