  2. Default gateway - Wikipedia

    en.wikipedia.org/wiki/Default_gateway

    If router1 routing table does not have any route to 192.168.1.0/24, and PC3 tries to access a resource outside its own network, then the outgoing routing will work until the reply is fed back to router1. Since the route is unknown to router1, it will go to router1's default gateway, and never reach router3.

  3. 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.

  4. Prefix delegation - Wikipedia

    en.wikipedia.org/wiki/Prefix_delegation

    For example, in a typical home network with legacy Internet Protocol version 4, the network prefix would be something like 192.168.1.0/24, as expressed in CIDR notation. With IPv4, commonly home networks use private addresses (defined in RFC 1918 ) that are non-routable on the public Internet and use address translation to convert to routable ...

  5. Gateway (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Gateway_(telecommunications)

    For example, if a private network has a base IPv4 address of 192.168.1.0 and has a subnet mask of 255.255.255.0, then any data addressed to an IP address outside of 192.168.1.0–192.168.1.255 is sent to the network gateway. IPv6 networks work in a similar way.

  6. Subnet - Wikipedia

    en.wikipedia.org/wiki/Subnet

    Creating a subnet by dividing the host identifier. A subnetwork, or subnet, is a logical subdivision of an IP network. [1]: 1, 16 The practice of dividing a network into two or more networks is called subnetting.

  7. IP routing - Wikipedia

    en.wikipedia.org/wiki/IP_routing

    IP routing is the application of routing methodologies to IP networks.This involves not only protocols and technologies but includes the policies of the worldwide organization and configuration of Internet infrastructure.

  8. Classless Inter-Domain Routing - Wikipedia

    en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

    Classless Inter-Domain Routing (CIDR / ˈ s aɪ d ər, ˈ s ɪ-/) is a method for allocating IP addresses for IP routing.The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet.

  9. 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.
