This is a list of countries by IPv4 address allocation. The Internet Assigned Numbers Authority (IANA) distributes large blocks of addresses to regional Internet registries (RIRs), which then assign them to national Internet registries and local Internet registries within their respective service regions.

A public IP address is a globally routable unicast IP address, meaning that the address is not an address reserved for use in private networks, such as those reserved by RFC 1918, or the various IPv6 address formats of local scope or site-local scope, for example for link-local addressing. Public IP addresses may be used for communication ...

The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol–related symbols and Internet numbers.
An IP range object represents an IPv4 or IPv6 range that overlaps with a sensitive IP range. IP range objects contain the following fields: range - the CIDR string representation of the range, e.g. "1.2.3.0/24" or "2001:d8::ffff:ab:0/16". type - the string "range" (used to differentiate between IP range objects and IP address objects).
IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referred to as TCP/IP.
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code.
