Summary
University of the Aegean
education university research legacy
The University of the Aegean (Πανεπιστήμιο Αιγαίου), a Greek public university that is unusual for being spread across six islands — Lesbos, Chios, Samos, Rhodes, Syros and Lemnos. The AS carries its campus network.
What it's used for
- Campus connectivity for the university's departments and schools. Roughly 8,000 IPv4 addresses across four /21s, single-homed to the Greek national research and education network.
- rDNS resolves under
aegean.grwhere it is delegated at all — much of the space returns nothing, which is normal for a campus that keeps most hosts on internal naming.
Notable
- Institutional address space: a stub academic AS with one upstream and no downstream customers. Nothing here is eyeball or hosting space.
- The four /21s are consecutive but not contiguous, which fits the geography: the university's departments are physically separated across the Aegean islands and each site was numbered as it came online.
- One of a cluster of Greek university ASNs allocated in the same range, next to AS8611 (Athens University of Economics and Business) and AS8618 (Ionian University).
Interesting
- Very few universities anywhere have to run their production network across a chain of islands. The Greek research network's inter-island links are what make a single AS possible here at all.

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 1,779 prefixes, as published 2026-10-23. 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.
