The gateway operates at the network layer (Layer 3) of the OSI Model.The gateway is used when transmitting packets.When packets are sent over a network, the destination IP address is examined.
A gateway is a network node that serves as an access point to another network, often involving not only a change of addressing, but also a different networking technology.
In Internet Protocol version 4 networks, broadcast addresses are special values in the host-identification part of an IP address.The all-ones value was established as the standard broadcast address for networks that support broadcast. [1]
In Internet networking, a private network is a computer network that uses a private address space of IP addresses.These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments.
A residential gateway is a small consumer-grade gateway which bridges network access between connected local area network (LAN) hosts to a wide area network (WAN) (such as the Internet) via a modem, or directly connects to a WAN (as in EttH), while routing.
A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, [1] they are used in several places, for example:
IP multicast address range Description Routable 224.0.0.0 to 224.0.0.255 Local subnetwork [3]: No 224.0.1.0 to 224.0.1.255 Internetwork control Yes
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
