Summary
Radiográfica Costarricense (RACSA)
isp legacy
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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,781 prefixes, as published 2026-10-16. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
