  2. Gateway address - Wikipedia

    en.wikipedia.org/wiki/Gateway_address

    The network host IP interface binds the gateway address to the MAC address of the physical gateway by broadcasting IP datagrams and caching the MAC address of the reply from the gateway in an ARP table stored on the host. The gateway address may be added manually. On Windows computers, the gateway address is configured using the TCP/IP Properties.

  3. Internet Protocol - Wikipedia

    It proposes the first version of the IP header, using 0 for the version field. IEN 26 A Proposed New Internet Header Format (February 1978) describes a version of the IP header that uses a 1-bit version field. IEN 28 Draft Internetwork Protocol Description Version 2 (February 1978) describes IPv2.

  4. Network address - Wikipedia

    en.wikipedia.org/wiki/Network_address

    Network diagram with IP network addresses indicated e.g. 192.168.100.3.. 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. [1]

  5. Private network - Wikipedia

    en.wikipedia.org/wiki/Private_network

    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. Both the IPv4 and the IPv6 specifications define private IP address ranges. [1] [2]

  6. Classless Inter-Domain Routing - Wikipedia

    en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

    An updated version, RFC 4632, was published in 2006. [ 5 ] After a period of experimentation with various alternatives, Classless Inter-Domain Routing was based on variable-length subnet masking (VLSM), which allows each network to be divided into subnetworks of various power-of-two sizes, so that each subnetwork can be sized appropriately for ...

  7. Default gateway - Wikipedia

    en.wikipedia.org/wiki/Default_gateway

    The IP-address could be 91.198.174.2. In this example, none of the internal routers know the route to that host, so they will forward the packet through router1's gateway or default route. [1] Every router on the packet's way to the destination will check whether the packet's destination IP-address matches any known network routes.

  8. Open Shortest Path First - Wikipedia

    en.wikipedia.org/wiki/Open_Shortest_Path_First

    NOTE: a RID is the highest logical (loopback) IP address configured on a router, if no logical/loopback IP address is set then the router uses the highest IP address configured on its active interfaces (e.g. 192.168.0.1 would be higher than 10.1.1.2). Usually the router with the second-highest priority number becomes the BDR.

  9. Routing table - Wikipedia

    en.wikipedia.org/wiki/Routing_table

    In this example, gateway 192.168.0.1 (the internet router) can be reached through the local network card with address 192.168.0.100. Finally, the Metric indicates the associated cost of using the indicated route. This is useful for determining the efficiency of a certain route from two points in a network.
