Summary

CARNet (Croatian Academic and Research Network)

Croatia · AI-generated

education research legacy

The Croatian Academic and Research Network (CARNET-AS, Hrvatska akademska i istraživačka mreža), Croatia's national research and education network (NREN), based in Zagreb.

What it's used for

  • Backbone connectivity for Croatian universities, schools, and research and public institutions.

Notable

  • A national research/education network, not a commercial ISP. The low AS number reflects an early-internet allocation for Croatia's academic community.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
