Historically, most larger Internet service providers, and all within the European RIPE NCC region require customers to be registered in an Internet Routing Registry prior to propagating BGP announcements of their routes. [4] This has not been a rigorously-enforced operational standard, however, and has declined since a peak in the early 2000s.
The RIPE NCC service region [3] consists of countries in Europe, the Middle East and parts of Central Asia. RIPE NCC services are available to users outside this region through Local Internet Registries; these entities must have a valid legal address inside the service region but can offer their services to anyone.

BGP is the standard routing protocol used to exchange information about IP routing between autonomous systems. Each AS uses BGP to advertise prefixes that it can deliver traffic to. For example, if the network prefix 192.0.2.0 / 24 is inside AS 64496, then that AS will advertise to its provider(s) and/or peer(s) that it can deliver any traffic ...
A provider-independent address space (PI) is a block of IP addresses assigned by a regional Internet registry (RIR) directly to an end-user organization. [1] The user must contract [2] with a local Internet registry (LIR) through an Internet service provider to obtain routing of the address block within the Internet.
RIB: routers main routing information base table. Loc-RIB: local routing information base BGP maintains its own master routing table separate from the main routing table of the router. Adj-RIB-In: For each neighbor, the BGP process maintains a conceptual adjacent routing information base, incoming, containing the NLRI received from the neighbor.
Some large / 8 blocks of IPv4 addresses, the former Class A network blocks, are assigned in whole to single organizations or related groups of organizations, either by the Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA), or a regional Internet registry.
The Latin America and Caribbean Network Information Centre (LACNIC) is based in Montevideo, Uruguay and serves Latin America as well as some Caribbean countries. [5] Réseaux IP Européens Network Coordination Centre (RIPE NCC) is based in Amsterdam, Netherlands and serves Central and West Asia, Europe, and Russia. [6]
Resource Public Key Infrastructure (RPKI), also known as Resource Certification, is a specialized public key infrastructure (PKI) framework to support improved security for the Internet's BGP routing infrastructure. RPKI provides a way to connect Internet number resource information (such as Autonomous System numbers and IP addresses) to a ...
