  2. 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.

  3. Wildcard mask - Wikipedia

    en.wikipedia.org/wiki/Wildcard_mask

    For example, a subnet mask of 255.255.255.0 (11111111.11111111.11111111.00000000 2) inverts to a wildcard mask of 0.0.0.255 (00000000.00000000.00000000.11111111 2). A wild card mask is a matching rule. [2] The rule for a wildcard mask is: 0 means that the equivalent bit must match; 1 means that the equivalent bit does not matter

  4. Subnet - Wikipedia

    en.wikipedia.org/wiki/Subnet

    For example, the subnet mask for a routing prefix that is composed of the most-significant 24 bits of an IPv4 address is written as 255.255.255.0. The modern standard form of specification of the network prefix is CIDR notation, used for both IPv4 and IPv6.

  5. Template:IPaddr - Wikipedia

    en.wikipedia.org/wiki/Template:IPaddr

    Template {{IPaddr}} is used to make an IP address stand out in the text, to improve readability. Template parameters [Edit template data] This template prefers inline formatting of parameters. Parameter Description Type Status IP address 1 The IP address to display, either IPv4 or IPv6. An IP address is displayed in italics, using lower case letters for IPv6 addresses. Example 198.51.100.52 or ...

  6. Internet Assigned Numbers Authority - Wikipedia

    en.wikipedia.org/wiki/Internet_Assigned_Numbers...

    The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address (e.g.IPV4, IPV6 but MAC Address) allocation so everyone has a unique identity (e.g. Registrar and Registrant) and will not be replicated, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol–related symbols ...

  7. 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]

    RFC 1918 name IP address range Number of addresses Largest CIDR block (subnet mask) Host ID size Mask bits Classful description [Note 1]; 24-bit block: 10.0.0.0 – 10.255.255.255: 16 777 216

  9. Open Shortest Path First - Wikipedia

    en.wikipedia.org/wiki/Open_Shortest_Path_First

    IS-IS, another LSR-based protocol, is more common in large service provider networks. Originally designed in the 1980s, OSPF version 2 is defined in RFC 2328 (1998). [1] The updates for IPv6 are specified as OSPF version 3 in RFC 5340 (2008). [2] OSPF supports the Classless Inter-Domain Routing (CIDR) addressing model.
