Information for LEAs

1. LACNIC and Law Enforcement Agencies (LEAs)

Given the growth of cybercrime in recent years, Regional Internet Registries (RIRs) are cooperating with Law Enforcement Agencies (LEAs) in various information and/or training instances to improve how public information is leveraged.

LACNIC cooperates with LEAs to address cybersecurity and public safety issues, fulfilling its responsibility as a critical actor within the Internet ecosystem.

LACNIC collaborates with these agencies both in training on cybersecurity issues as well as in data localization, available via the WHOIS service. In this sense, LACNIC CSIRT serves as an intermediary for law enforcement agencies to locate and interpret public information on LACNIC member organizations.

2. What information can LACNIC provide?

Generally speaking, the information that LACNIC can provide is publicly available and can be accessed through the WHOIS service.

Other than the information available in the WHOIS database, LACNIC has very little additional information on its members (organizations that received IP addresses directly from LACNIC). This information, for example, might be the name of the organization's legal representative or billing contact.

For reasons of confidentiality, what little additional information LACNIC can provide must be requested by court order. Before requesting a court order, we first suggest checking our LACNIC's authority and what additional information the organization can provide. (LACNIC´s Authority).

Below you will find an overview of the type of publicly accessible information that LACNIC can provide to LEAs and the guidelines for obtaining such information:

  1. List of LACNIC member organizations
  2. Public information on LACNIC member organizations, available in the WHOIS database To interpret the data published via the WHOIS service, we suggest you refer to the following information:  

If you have any doubts or if you can't find the information you are looking for, please complete the following form and LACNIC CSIRT staff will contact you shortly.

3. LACNIC's Authority

LACNIC is the organization responsible for the registration and assignment of Internet number resources (IPv4 and IPv6 addresses, ASNs) for Latin America and the Caribbean. In this context, LACNIC collaborates with LEAs to locate and interpret the data of its member organizations that is available via the WHOIS service.

It is important to stress that LACNIC does not have the authority to act on the operations of the systems of its member organizations except for its own internal systems. In this sense and by way of an example, LACNIC has no information on who operates the domain names or the clients of an Internet service provider (ISP), nor the authority to block a website even if one of its member organizations is involved.
