Data type Range Default value
REG_SZ IPAddress[ IPAddress...] (A-space delimited list of dotted decimal IP addresses.) (There is no default value for this entry. The value is configured by DHCP.)


Stores a list of DNS servers to which Windows Sockets sends queries when it resolves names for the interface. The value of this entry is configured for the interface by DHCP, but can overridden by a different valid value configured by the user.

The interface-specific DNS name server for the system is determined by the values of DhcpNameServer, which is configured by DHCP, and by NameServer, which you can configure.

If all entries contain valid values, the user-configured values take precedence over the DHCP-configured values configuring the affected interface.
