LACNIC:What is it and what does it do?

Updated: Jul 5, 2023

LACNIC is the regional Internet registry for Latin America and the Caribbean; (Latin America and Caribbean. Where the global operation of the Internet is supported by the number resource allocation and registration services offered by LACNIC. Internet Service Providers and other similar organizations are members of this non-profit, membership-based organization.

LACNIC Functions

The primary duties of LACNIC are:

- Distributing IPv4 and IPv6 address space as well as ASNs.

- Upkeep of the public Whois database for the region of Latin America and the Caribbean.

- Delegations in reverse DNS

- Addressing the online community's needs in Latin America and the Caribbean on a global scale

LACNIC Formation

Since 1993, academic organizations in Latin America have debated the necessity for a register for the region that is free from American influence, such as ENRED, They learned that another group formed by commercial organizations like CABASE (Cámara), and ECOM-LAC (Latin America and Caribbean Federation for Internet and Electronic Commerce) were also debating the idea of a Latin American registry during a 1998 ENRED meeting in Panama that included NIC-MX.

Ira Magaziner, then President Clinton's chief policy adviser, issued a discussion paper on January 30, 1998, which became known as the "green paper" in response to the DNS root authority event.

On June 5, the "white paper," an updated version, was made public. This essay suggested a new entity to manage internet resources (that later became ICANN). South American communication groups attended the final of four meetings that the International Forum for the White Paper arranged, which was held in Buenos Aires.

The agreement for the establishment of LACNIC was signed in Santiago de Chile on August 22, 1999, during the second ICANN meeting, by the organizations that ECOM-LAC was a part of. These groups contended that Latin American IP addresses might be managed by a local entity.

A six-member interim board was established as follows:

On August 26, 1999, Esther Dyson, the interim board chair at the time, received the agreement to form LACNIC, and the business plan was delivered to ARIN. The establishment of statutes led to the decision that the LACNIC headquarters would be in Montevideo, with technicians and equipment located at the facilities in So Paulo. With administrative headquarters in Montevideo, Uruguay, and technical infrastructure supplied by CGI. LACNIC was founded officially in 2001. ICANN publicly acknowledged the requirements for a new regional Internet registry during its Shanghai summit in 2002.

Exhaustion of IPv4

LACNIC declared that IPv4 availability had reached a critical low threshold on June 10, 2014.

The association then voiced worry about the fact that local administrations and service providers were postponing the adoption of IPv6. LACNIC is now obliged to delegate addressed in a more cautious manner after reaching the 4 millionth milestone. In total, LACNIC has distributed more than 182 million IPv4 addresses since its founding in 2002.

LACNIC Membership

Currently, LACNIC includes approximately 8,500 members

LACNIC Membership Categories

Internet Service Provider (ISP)

Internet service providers offering web hosting, co-location, VPS services, and dedicated links. The resources are then assigned to their customers. This category is defined by the number of assigned IPv4 or IPv6 addresses.

End User

Banks, government agencies, universities, etc. The resources are used for their own infrastructure and addresses are not sub-assigned to third parties. This category is defined by the number of assigned IPv4 or IPv6 addresses.

Adhering Member

An organization or individual that becomes a LACNIC member without requesting IP addresses.


Any type of organization legally established in the LACNIC region may request an autonomous system (AS). An AS is a collection of IP address networks that presents a clearly defined and unique routing policy to the Internet. Each AS has an associated number which is used as its identifier when exchanging external routing information.

Policy development

LACNIC operates based on a self-regulation model according to which the rules or policies governing Internet resource administration are developed by the community through a public, participation and transparent process. This process is open to anyone who wishes to take part in it and is built on the achievement of consensus.

Open participation of all stakeholders ensures that these policies are in line with the interests of the Region, thus safeguarding the community as a whole. Before being presented at the forums to gain consensus, all proposals are submitted and discussed on the policy mailing list.

To be approved, a proposal must reach consensus both on the discussion list and at the forum.

A proposal may modify either the policy manual or the Policy Development Process (PDP) itself.

The policy manual is the public document that includes all the policies that have been implemented in the LACNIC region and that determine how we must manage resources.

The PDP validates the creation and modification of the policies that the RIR will apply within its region.
