    What is the netblock IPV4 databases?

    You can find all major IP addresses blocks allocated for any country. Most of these IP blocks are assigned for Internet providers and hosting companies.

    What is the Regional Internet registry?

    A regional Internet registry (RIR) is an organization that manages the allocation and registration of Internet number resources within a particular region of the world. Internet number resources include IP addresses and autonomous system (AS) numbers.


    This document provides information about the current Internet Numbers Registry System used in the distribution of globally unique Internet Protocol (IP) address space and autonomous system (AS) numbers. This document also provides information about the processes for further evolution of the Internet Numbers Registry System.

    Goals:

    • Allocation Pool Management
    • Hierarchical Allocation
    • Registration Accuracy

    Internet Numbers Registry System Structure

    The Internet Registry (IR) hierarchy was established to provide for the allocation of IP addresses and AS numbers, This hierarchy is rooted in the Internet Assigned Numbers Authority (IANA) address allocation function, which serves a set of "Regional Internet Registries" (RIRs); the RIRs then serve a set of "Local Internet Registries" (LIRs) and other customers. LIRs in turn serve their respective number resource consumers (which may be themselves, their customers, "sub-LIRs", etc.)

    IETF

    The IETF specifies the underlying technical facilities and constraints of Internet numbers administered by the Internet Numbers Registry System. The IETF has also reserved portions of the Internet number spaces and identifiers for future needs.

    IANA

    The Internet Assigned Numbers Authority (IANA) is a role, not an organization. For the Internet Numbers Registry System, the IANA role manages the top of the IP address and AS number allocation hierarchies 

    Regional IRs

    The RIRs operate in continent-sized geopolitical regions. Currently, there are five RIRs: AfriNIC serving Africa, APNIC serving parts of Asia and the Pacific region, ARIN serving North America and parts of the Caribbean, LACNIC serving Latin America and parts of the Caribbean, and RIPE NCC serving Europe, parts of Asia and the Middle East.

    Local IRs

    Local Internet Registries (LIRs) are established through a relationship with the body from which they received their addresses, typically the RIR that serves the region in which they operate, a parent LIR, or other number-allocating entity.
