Summary
International Hellenic University
education university legacy
TEI-THES is the campus network of what is now the International Hellenic University in Thessaloniki, Greece.
What it's used for
- Campus, teaching, and administrative networking for the university's schools and departments in the Thessaloniki area.
- Student and staff access, library and lab resources, and the institution's public-facing services.
Notable
- The handle preserves the network's origin as the Technological Educational Institute (TEI) of Thessaloniki. Greece's 2019 reform of tertiary education merged the TEI into the International Hellenic University, and the AS carried on under the new institution without a handle change.
- Greek university networks generally reach the wider internet through GRNET, the national research and education network, rather than buying commercial transit.

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.
