NSHost class provides methods to access the network name and address information for a host. Instances of the
NSHost class represent individual hosts on a network. Use
NSHost objects to get the current host’s names and addresses and to look up other hosts by name or by address.

To create an
NSHost object, use the
init(name:) class methods (don’t use
init). These methods use available network administration services to discover all names and addresses for the host requested. They don’t attempt to contact the host itself, however. This approach avoids untimely delays due to a host being unavailable, but it may result in incomplete information about the host.
NSHost object contains all of the network addresses and names discovered for a given host by the network administration services. Each
NSHost object may contain several addresses and have more than one name. If an
NSHost object has more than one name, the additional names are variations on the same name, typically the basic host name plus the fully qualified domain name. For example, with a host name
"sales" in the domain
NSHost object can hold both the names
NSHost methods are thread-safe.
