+Raíces Project

Project goals

The main goal of the +Raices project is the installation of anycast root server copies in various countries of the LACNIC region. By installing these servers at strategic locations throughout the region such as IXPs (Internet Exchange Points) and NAPs (Network Access Points), the project seeks to achieve greater resiliency for one of the Internet's most critical resources, the DNS. It provides redundancy and reduces criticality, allowing a better response in case of potential DDoS attacks or eventual infrastructure failures that could render certain root servers inoperative.

LACNIC's Role

LACNIC's role is to coordinate with host organizations and those providing the root servers, as well as to promote these new root servers. In certain cases, LACNIC may sponsor the installation of a root server copy.

About the project

This initiative is part of LACNIC's active role as a promoter of regional Internet development. The +Raices project helps strengthen global Internet infrastructure and stability. In other words, it broadens the scope and improves the strength and response times of the DNS system (an essential part of Internet infrastructure) at both regional and global level. For this reason, LACNIC has signed the following agreements:

Structure

The Domain Name System (DNS) is based on a hierarchical tree-like structure in which millions of servers worldwide have part of the information needed to make the system work.

At the root of this system there is not one but thirteen servers performing this function, each of which is identified with the letters A to M. These thirteen servers share the same hierarchy and none is subordinated to another. Ten are located in the United States, two in Europe, and one in Japan. The small number of these servers and the fact that they are highly concentrated in the US represent a weakness in terms of safety and stability, especially when considering DDoS attacks.

Anycast

Anycast has long been used as a way to announce the same prefix from several different locations. The routing system can then identify which location is closest to each user. A few years ago, this technique began to be used as a way to create root server "clones," thus overcoming the technical limitations that do not allow implementing new logical root servers.

Users only see the root server closest to them, not the original server or other copies. This increases the system's efficiency while providing greater security and stability. If for some reason an anycast copy of a root server fails, users will automatically start seeing other copies or other root servers.

How to participate in +RAICES

If you would like to host an anycast root server copy, please contact LACNIC at raices@lacnic.net. In order to better process your request, we recommend providing a brief description of your organization and how it connects to the Internet.

Requirements

Dell PowerEdge servers with iDRAC interface v7 or above for remote administration. The server requires three network interfaces:

  • iDRAC interface
  • Gigabit Ethernet interface for system management
  • Gigabit Ethernet interface for production (anycast traffic)

IPv4 and IPv6 connectivity are both required. The host organization must provide:

  • A global IPv4 address (routable) for iDRAC, IPv6 is not required
  • For interface management, either an IPv6 address with NAT64/DNS64 or an IPv4 and an IPv6 address are required.
  • The production interface also requires an IPv4 address (and eventually an IPv6 address), which may be private, to connect with the host institution's BGP neighbor.

This BGP session will be used to announce the anycast prefixes, which for the K root server as follows:

  • 193.0.14.0/24
  • 2001:7FD::/48
  • ASN 25152
