IP address allocation follows the hierarchical scheme described in RFC 2050. For the region of Latin America and the Caribbean, IP address space is allocated by IANA to LACNIC for its subsequent allocation and assignment to National Internet Registries (NIRs), Internet Service Providers (ISPs), and end users. In addition, administration of Autonomous System Numbers and reverse resolution space are critical components for the efficient operation of the Internet on a global level. This document describes the policies and procedures relating to the allocation, assignment and administration of IPv4 and IPv6 address space, ASN, and the delegation of the reverse resolution space assigned to Latin America and the Caribbean. These policies must be followed by NIRs, ISPs, and end users.
