AS6400 Compania Dominicana de Telefonos S. A.

AS6400 belongs to Compañía Dominicana de Teléfonos, S. A. (CODETEL) — the incumbent telecommunications operator of the Dominican Republic, today trading as Claro under América Móvil. It is the country's largest network.

What it's used for

• Residential and business internet across the Dominican Republic: fibre, DSL and other fixed broadband.
• The operator's wider telecom infrastructure, carrying roughly 800 thousand IPv4 addresses across more than a hundred prefixes, plus IPv6.
• Address space drawn from both Latin American (190.x, 148.x) and older 196.3.x allocations.

Notable

This is national-incumbent eyeball space. Geolocation resolves broadly across the Dominican Republic rather than to any one facility, and the traffic profile is consumer-shaped. As the dominant carrier, it also carries a large share of the country's business and government connectivity, so not every address here is a household.

Address resources for the network are administered through LACNIC, the Latin American and Caribbean registry, even though the AS number itself sits in an ARIN-era range — an artefact of LACNIC being carved out of ARIN's remit in the early 2000s and inheriting existing regional resources.
