Setting the Name Server
Naming services are used to associate IP addresses with hostnames. Many networks use the Domain Name System (DNS) or the Network Information Service (NIS) for mapping hostnames to IP addresses. Both services are used to identify and locate objects and resources on the network. To use DNS or NIS, you must specify the IP address of the name server during the configuration process.
The PortMaster stores all information by address rather than name. To disable the use of a name service, set the name server's IP address to 0.0.0.0.
