LACNIC, the Internet Address Registry for Latin America and the Caribbean, manages IPv4 / IPv6 addresses and ASNs using the policy development process defined by the Internet community.

The Latin American and Caribbean Internet Addresses Registry is an international, non-governmental organization established in Uruguay in 2002. It is responsible for assigning and managing Internet number resources (IPv4, IPv6), Autonomous System Numbers, and Reverse Resolution for the region.

LACNIC contributes to regional Internet development through an active cooperation policy. It promotes and defends the interests of the regional community and helps create conditions for the Internet to function as an effective instrument for social inclusion and economic development in Latin American and the Caribbean.

It is managed and run by a board of seven directors elected by LACNIC members. This group of members comprises more than 12,500 network operators who provide services in 33 Latin American and Caribbean territories.
