An organization’s IT ecosystem is the network of services, providers and other organizations connected to the organization that create and deliver information technology products and services. This ecosystem includes entities that are connected to but not controlled directly by the organization, such as a third-party vendor, an independent subsidiary or a company added via merger or acquisition. Cloud computing resources used by the organization are also part of its IT ecosystem. All of the assets associated with all of the IT ecosystem entities define the organization’s attack surface.
IPv6 is a 128-bit number developed by the Internet Engineering Task Force (IETF) to help deal with the long-anticipated problem of IPv4 address exhaustion.

An IPv4 address is a 32-bit number that uniquely identifies a network interface used to connect a machine to the Internet or local area network. This is the fourth version of the Internet Protocol used for internetworking. An IPv4 address consists of four sets of numbers ranging from 0 to 255, which communicate the location of the device, router, and website.
Ubiquitous computing and proliferation of devices such as those created by mobile devices and the so called Internet of Things (IoT) depleted the over 4 billion IPv4 numbers in February 2011 which is known as IPv4 address exhaustion.
IP Addresses are mathematically calculated and assigned by the Internet Assigned Numbers Authority (IANA), which is a division of the Internet Corporation for Assigned Names and Numbers (ICANN).
