About this network

RACSA (Radiográfica Costarricense S.A.) is a Costa Rican state-owned telecommunications and digital services company, a subsidiary of the national electricity and telecom utility ICE.

What it's used for

• Internet access and connectivity for Costa Rican homes, small businesses, and public sector institutions.
• Digital and managed IT services for government and enterprise customers, which is an increasingly large share of what RACSA sells.

Notable

• Announces on the order of 100,000 IPv4 addresses, a mid-sized national operator footprint.
• One of the older names in Costa Rican networking: RACSA began as the country's international telegraph and radio-telegraph operator, and the "Radiográfica" in the name is a leftover from that era.

Interesting

• RACSA has repositioned over the years from being Costa Rica's dominant early internet provider toward digital services and fixed wireless access, so the mix of the address space has shifted away from pure dial-up-era eyeball customers.
