Latin American and Caribbean Internet Addresses Registry (LACNIC) is one of the five regional RIRs that allocate and administer IP Addresses.[1] LACNIC's central aim is to manage Internet number resources, including IPv4, IPv6, and ASN. The organization has approximately 6,000 members spread across 33 countries.[2]


LACNIC is the RIR (Regional Internet Registry) responsible for the allocation of IP addresses and other related issues (such as the Autonomous System Numbers and Reserve Resolution) throughout the Latin American and Caribbean region.

LACNIC is a non-profit organization like the other RIRs and its members must comply with its membership requirements. The main members of LACNIC are ISPs and other Internet related organizations.

As of January, 2011 LACNIC has begun DNSSEC Deployment.[3]

LACNIC History

The agreement for founding LACNIC was signed on August 22nd, 1999 during an ICANN meeting. At that time, ARIN was in charge of the Latin America and Caribbean region. Thus, LACNIC developed a business plan and sent it to ARIN; a transition was necessary to enable LACNIC to become the fourth RIR at that time. The other three RIRs at that time were: APNIC, ARIN, and RIPE NCC.[4]

LACNIC headquarters are located in Montevideo, Uruguay, and it was formally established in 2001, even though the business plan was sent and approved in 1999. LACNIC was formally recognized by ICANN during ICANN's 2002 meeting in Shanghai.

In January, 2012, LACNIC published a letter explaining its opposition to the much maligned SOPA act being considered in the U.S. Congress.[5]

LACNIC Functions

In order to fulfill its objectives, LACNIC has the following expectations:

  • To deal with DNS delegations which must be reversed;
  • To allocate the appropriate amount of Internet addresses spaces according to IPv6 and IPv4 standards, as well as Autonomous System Numbers;
  • To represent the interests of Internet users and members of the Latin American and Caribbean regions at a global level;
  • To maintain the Whois database representative for the Latin American and Caribbean region.

LACNIC Structure

The structure of LACNIC consists of:

  • The LACNIC members: Influence the activities and services of LACNIC as well as elect candidates to the Executive Board of LACNIC. They are also empowered through their ability to accept new plans and annual finances.
  • General Assembly: LACNIC ruling body
  • Board of Director with an Executive Director subordinated: These directors are nominated and elected by LACNIC members. The Board of Directors consists of six members who eventually appoint the Executive Director.
  • Control Organ: Manages and analyzes the activities and actions of the Board of Directors.
  • Electoral Commission: In charge of organizing all elections, it consists of three members. [6]

IPv4 Exhaustion

On June 10, 2014, LACNIC announced that IPv4 availability had hit a critical low point.The organization then expressed concern over the fact that regional governments and providers were delaying the implementation of IPv6. Reaching the 4 millionth mark, LACNIC is now forced to delegate addressed in a more conservative manner. Since its beginning in 2002, LACNIC has dispersed over 182 million IPv4 addresses. [7]
