title: Network address text: Network address A network address is an identifier for a node or host on a telecommunications network. Network addresses are designed to be unique identifiers across the network, although some networks allow for local, private addresses or locally administered addresses that may not be unique. Special network addresses are allocated as broadcast or multicast addresses. These too are not unique. In some cases, network hosts may have more than one network address; for example, each network interface may be uniquely identified. Further, because protocols are frequently layered, more than one protocol's network address can occur in any particular network interface title: Network Information Service text: Network Information Service The Network Information Service, or NIS (originally called Yellow Pages or YP), is a client–server directory service protocol for distributing system configuration data such as user and host names between computers on a computer network. Sun Microsystems developed the NIS; the technology is licensed to virtually all other Unix vendors. Because British Telecom PLC owned the name "Yellow Pages" as a registered trademark in the United Kingdom for its paper-based, commercial telephone directory, Sun changed the name of its system to NIS, though all the commands and functions still start with "yp". A NIS/YP system maintains and title: Routing table text: Routing table In computer networking a routing table, or routing information base (RIB), is a data table stored in a router or a networked computer that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes. The routing table contains information about the topology of the network immediately around it. The construction of routing tables is the primary goal of routing protocols. Static routes are entries made in a routing table by non-automatic means and which are fixed rather than being the result of some network topology "discovery" procedure. A routing table uses title: Network address text: or node and more than one type of network address may be used in any one network. Examples of network addresses include: Network address A network address is an identifier for a node or host on a telecommunications network.

The standard syntax is "user@realm". Sample NAIs include (from RFC 4282): Network Access Identifiers were originally defined in RFC 2486, which was superseded by RFC 4282, which has been superseded by RFC 7542. The latter RFC is the current standard for the NAI. NAIs are commonly found as user identifiers in the RADIUS and Diameter network access protocols and the EAP authentication protocol. The Network Access Identifier (NAI) is the user identity submitted by the client
