NSNetService represents a network service that applications either publish or use as a client. A network service can be anything such as FTP, Telnet, SSH, HTTP, or any of the well-known services. A service can also be something of your own design. NSNetService provides application level access to the low-level Multicast DNS responder APIs. For more information about Rendezvous and the Net Services APIs in Foundation, see Chapter 6.
