  2. Broadcast address - Wikipedia

    en.wikipedia.org/wiki/Broadcast_address

    A broadcast address is a network address used to transmit to all devices connected to a multiple-access communications network. A message sent to a broadcast address may be received by all network-attached hosts. In contrast, a multicast address is used to address a specific group of devices, and a unicast address is used to address a single ...

  3. Default gateway - Wikipedia

    en.wikipedia.org/wiki/Default_gateway

    The default gateway can be specified by the route command to configure the node's routing table and default route. In a home or small office environment, the default gateway is a device, such as a DSL router or cable router, that connects the local network to the Internet. It serves as the default gateway for all network devices.

  4. Gateway address - Wikipedia

    en.wikipedia.org/wiki/Gateway_address

    The gateway address (or default gateway) is a router interface connected to the local network that sends packets out of the local network. The gateway has a physical and a logical address. The gateway has a physical and a logical address.

  6. Classful network - Wikipedia

    en.wikipedia.org/wiki/Classful_network

    The number of addresses usable for addressing specific hosts in each network is always 2 N - 2, where N is the number of rest field bits, and the subtraction of 2 adjusts for the use of the all-bits-zero host value to represent the network address and the all-bits-one host value for use as a broadcast address. Thus, for a Class C address with 8 ...

  7. Broadcasting (networking) - Wikipedia

    en.wikipedia.org/wiki/Broadcasting_(networking)

    In computer networking, telecommunication and information theory, broadcasting is a method of transferring a message to all recipients simultaneously. Broadcasting can be performed as a high-level operation in a program, for example, broadcasting in Message Passing Interface, or it may be a low-level networking operation, for example broadcasting on Ethernet.

  8. Bootstrap Protocol - Wikipedia

    en.wikipedia.org/wiki/Bootstrap_Protocol

    A broadcast IP datagram cannot pass through any router. The router discards this packet. To solve this problem, there is a need for an intermediary (relay). One of the host or router can be configured at application layer to operate as relay agent. The relay agent knows the uni-cast address of bootp server and listens for broadcast message on ...

  9. Multicast address - Wikipedia

    en.wikipedia.org/wiki/Multicast_address

    In support of link-local multicasts which do not use IGMP, any IPv4 multicast address that falls within the *.0.0.0 / 24 and *.128.0.0 / 24 ranges will be broadcast to all ports on many Ethernet switches, even if IGMP snooping is enabled, so addresses within these ranges should be avoided on Ethernet networks where the functionality of IGMP ...
