2. Classless Inter-Domain Routing - Wikipedia

   en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

   Classless Inter-Domain Routing (CIDR / ˈsaɪdər, ˈsɪ -/) 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. Its goal was to slow the growth of routing tables on routers across the Internet, and ...

3. Domain masking - Wikipedia

   en.wikipedia.org/wiki/Domain_Masking

   Domain masking or URL masking is the act of hiding the actual domain name of a website from the URL field of a user 's web browser in favor of another name. [ 1] There are many ways to do this, including the following examples. HTML inline frame or frameset so a frame embedded in the main website actually points to some other site.

4. IP address - Wikipedia

   en.wikipedia.org/wiki/IP_address

   An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [1][2] IP addresses serve two main functions: network interface identification, and location addressing. Internet Protocol version 4 (IPv4) defines an IP ...

5. Subnet - Wikipedia

   en.wikipedia.org/wiki/Subnet

   Subnet. 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. Computers that belong to the same subnet are addressed with an identical group of its most-significant bits of their IP addresses. This results in the logical division of an IP ...

6. Routing table - Wikipedia

   en.wikipedia.org/wiki/Routing_table

   In computer networking, a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes. The routing table contains information about the topology of the network immediately ...

7. Reserved IP addresses - Wikipedia

   en.wikipedia.org/wiki/Reserved_IP_addresses

   Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255

8. List of assigned /8 IPv4 address blocks - Wikipedia

   en.wikipedia.org/.../8_IPv4_address_blocks

   Each / 8 block contains 256 3 = 2 24 = 16,777,216 addresses, which covers the whole range of the last three delimited segments of an IP address. This means that 256 /8 address blocks fit into the entire IPv4 space. As IPv4 address exhaustion has advanced to its final stages, some organizations, such as Stanford University, formerly using 36.0.0 ...

9. Multicast address - Wikipedia

   en.wikipedia.org/wiki/Multicast_address

   A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (layer 3 for OSI ...
