  2. Subnet - Wikipedia

    en.wikipedia.org/wiki/Subnet

    The subnet router anycast address is the lowest address in the subnet, so it looks like the “network address”. If a router has multiple subnets on the same link, then it has multiple subnet router anycast addresses on that link. [19] The first and last address in any network or subnet is not allowed to be assigned to any individual host.

  3. Screened subnet - Wikipedia

    en.wikipedia.org/wiki/Screened_subnet

    In network security a screened subnet refers to the use of one or more logical screening routers as a firewall to define three separate subnets: an external router (sometimes called an access router), that separates the external network from a perimeter network, and an internal router (sometimes called a choke router) that separates the ...

  4. 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. Distributed software must be designed to be partition-tolerant, that is, even after the network is partitioned, it still works correctly.

  5. DMZ (computing) - Wikipedia

    en.wikipedia.org/wiki/DMZ_(computing)

    In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network or screened subnet) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to an untrusted, usually larger, network such as the Internet.

  6. Private VLAN - Wikipedia

    en.wikipedia.org/wiki/Private_VLAN

    There is a need to preserve IP addressing. With Private VLANs, all Secondary VLANs can share the same IP subnet. Overcome license fees for number of supported VLANs per firewall. [5] There is a need for more than 4095 segregated networks. With Isolated VLAN, there can be endless number of segregated networks. [6]

  7. Network segmentation - Wikipedia

    en.wikipedia.org/wiki/Network_segmentation

    Network segmentation in computer networking is the act or practice of splitting a computer network into subnetworks, each being a network segment. Advantages of such splitting are primarily for boosting performance and improving security.

  8. Internet - Wikipedia

    en.wikipedia.org/wiki/Internet

    Creating a subnet by dividing the host identifier. A subnetwork or subnet is a logical subdivision of an IP network. [83]: 1, 16 The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP

  9. VLAN - Wikipedia

    en.wikipedia.org/wiki/VLAN

    In this way, VLANs can keep network applications separate despite being connected to the same physical network, and without requiring multiple sets of cabling and networking devices to be deployed. VLANs allow network administrators to group hosts together even if the hosts are not directly connected to the same network switch .
