Summary
Aristotle University of Thessaloniki
education university research legacy
ASAUTHNET / AUTH-NET-AS — the campus network of the Aristotle University of Thessaloniki (AUTH), the largest university in Greece.
What it's used for
- Campus connectivity for AUTH's schools and faculties, research groups, libraries, computer centres and student services.
Notable
- A big institutional network: AUTH holds far more address space than most single organisations, which is the mark of a university that received its allocation when addresses were handed out generously and every machine on campus expected a public IP.
- The university's connectivity to the wider internet runs through GRNET, the Greek national research and education network, as is standard for Greek institutions.
Interesting
- The scale here is the story. One campus in northern Greece is carrying an address block on the order of a mid-sized ISP's, purely because it was early.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
