  2. Subnet - Wikipedia

    en.wikipedia.org/wiki/Subnet

    [4] [5] IPv6 address assignment to an interface carries no requirement of a matching on-link prefix and vice versa, with the exception of link-local addresses. Since each locally connected subnet must be represented by a separate entry in the routing tables of each connected router, subnetting increases routing complexity.

  3. Subnet (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Subnet_(mathematics)

    There are several different non-equivalent definitions of "subnet" and this article will use the definition introduced in 1970 by Stephen Willard, [1] which is as follows: If = and = are nets in a set from directed sets and , respectively, then is said to be a subnet of (in the sense of Willard or a Willard–subnet [1]) if there exists a monotone final function: such that = ().

  4. IP address - Wikipedia

    en.wikipedia.org/wiki/IP_address

    Both IP versions however use the CIDR concept and notation. In this, the IP address is followed by a slash and the number (in decimal) of bits used for the network part, also called the routing prefix. For example, an IPv4 address and its subnet mask may be 192.0.2.1 and 255.255.255.0, respectively.

  5. Von Neumann architecture - Wikipedia

    en.wikipedia.org/wiki/Von_Neumann_architecture

    A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.

  6. Control plane - Wikipedia

    en.wikipedia.org/wiki/Control_plane

    When an interface has an address configured in a subnet, such as 192.0.2.1 in the 192.0.2.0/24 (i.e., subnet mask 255.255.255.0) subnet, and that interface is considered "up" by the router, the router thus has a directly connected route to 192.0.2.0/24. If a routing protocol offered another router's route to that same subnet, the routing table ...

  7. Network partition - Wikipedia

    en.wikipedia.org/wiki/Network_partition

    A network partition is a division of a computer network into relatively independent subnets, either by design, to optimize them separately, or due to the failure of network devices.

  8. Supernetwork - Wikipedia

    en.wikipedia.org/wiki/Supernetwork

    In another example, an ISP is assigned a block of IP addresses by a regional Internet registry (RIR) of 172.1.0.0 to 172.1.255.255. The ISP might then assign subnetworks to each of their downstream clients, e.g., Customer A will have the range 172.1.1.0 to 172.1.1.255, Customer B would receive the range 172.1.2.0 to 172.1.2.255 and Customer C ...

  9. Broadcast address - Wikipedia

    en.wikipedia.org/wiki/Broadcast_address

    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] This method of using the all-ones address was first proposed by R. Gurwitz and R. Hinden in 1982. [2]
