Name: DNSServers

Type: function

Syntax: the DNSServers

Syntax: DNSServers()

Summary: <return|Returns> a list of the <DNS> servers listed in the system's <TCP|TCP/IP> network configuration.

Introduced: 2.0

OS: mac,windows,linux

Platforms: desktop,server,web

Example:

put the DNSServers into myDNSList

Returns: The <DNSServers> <function> <return|returns> a list of <IP address|IP addresses>, one per line.

Description:

Use the <DNSServers> <function> to find the <IP address> of the <server|servers> that will be used to translate <IP address|IP addresses> into <domain name|domain names>.

>*Cross-platform note:* On <Mac OS|Mac OS systems>, the <DNSServers> <function> returns only the first <IP address>.

When an application requests contact with a system specified by its domain name, the domain name must first be translated into an IP address. 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.)

Since the <DNSServers> <function> reads the value set in the network configuration, it is available even if the system is not currently connected to the <Internet>.
