Argentina's inter-university network, run by ARIU (Asociación de Redes de Interconexión Universitaria), the association of national universities that are members of the CIN. It provides the academic backbone linking Argentine universities.
What it's used for
- Connecting Argentina's national universities and university institutes to each other and, via InnovaRed and RedCLARA, to international research networks.
Notable
- An IP here is institutional academic networking for Argentine universities, classified
educationrather than commercial hosting even though the backbone operationally resembles a carrier network.
Interesting
- RIU has operated as a shared university backbone since the 1990s, reaching regional advanced research networks through Latin America's RedCLARA.

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 1,783 prefixes, as published 2026-10-20. 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.
