    The "Map of the Internet Project" maps over 4 billion internet locations as cubes in 3D cyberspace. Users can add URLs as cubes and re-arrange objects on the map. In early 2011 Canadian based ISP PEER 1 Hosting created their own Map of the Internet that depicts a graph of 19,869 autonomous system nodes connected by 44,344 connections.

    en.wikipedia.org/wiki/Availability_zone

    Availability zones are typically geographically separated from one another, to prevent local disasters from acting on more than one availability zone. Some service providers also make higher-level regional distinctions between availability zones, allowing service providers to mitigate even regional-level disasters such as earthquakes and forest ...

  4. Network segmentation - Wikipedia

    en.wikipedia.org/wiki/Network_segmentation

    Reduced congestion: On a segmented network, there are fewer hosts per subnetwork and the traffic and thus congestion per segment is reduced; Improved security: Broadcasts will be contained to local network. Internal network structure will not be visible from outside.

    IPv4 address exhaustion timeline. IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses.Because the original Internet architecture had fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s when the Internet started experiencing dramatic growth.
