Identifies the network protocol address of a network object.

When a connection is made, the client and the receiver of the request (listener, Oracle Names server, or Oracle Connection Manager) are configured with identical protocol addresses. The client uses this address to send the connection request to a particular network object location, and the recipient "listens" for requests on this address.

The following address defines a listening address for the listener.

(address=
 (protocol=tcp)
 (host=sales-pc)
 (port=1521))
