Summary
ACOnet (Austrian Academic Computer Network)
education research legacy
ACOnet, Austria's national research and education network (NREN), which connects the country's universities and research institutions. The handle references ACOnet services at the Vienna Internet eXchange (VIX), the national internet exchange it also operates.
What it's used for
- National backbone and internet connectivity for Austrian universities, research institutes, and other academic organizations.
Notable
- An NREN and exchange operator, not a commercial ISP. The low AS number reflects an early allocation from the RIPE region's early years.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
