Internet in the Dominican Republic: Overview
The Dominican Republic is one of the leading countries in connectivity in the Caribbean, with over 8 million internet users and penetration near 75%. The country has experienced rapid modernization of its telecommunications infrastructure in the last decade, with significant fiber optic expansion in Santo Domingo, Santiago, Punta Cana, and other major cities. INDOTEL (Instituto Dominicano de las Telecomunicaciones) has driven competition policies that have improved services.
The Dominican market is dominated by three major operators: Claro Dominicana (América Móvil, the largest with over 5 million customers), Altice (formerly Tricom and Orange, the fiber optic leader), and Viva (a local operator). IP blocks assigned to the country include 186.0.0.0/13, 181.0.0.0/14, and 201.0.0.0/13. The Dominican Republic stands out in the Caribbean for having relatively good internet speeds (national average 25-35 Mbps) and growing IPv6 adoption (10-15%).
A particularity of Dominican IPs is that they frequently appear geolocated in Puerto Rico or the United States in some databases, because Claro shares regional infrastructure with América Móvil. This can cause problems with services like Netflix and online banking. miip.link helps verify the true location of your Dominican IP.
