Summary
University of Bucharest
education university research legacy
UNIBUC is the autonomous system of Universitatea din București (the University of Bucharest), Romania's largest and one of its oldest universities.
What it's used for
- Campus networking for the university's faculties, libraries, laboratories and administration across its Bucharest sites.
- Announces a handful of
/24s drawn from several different Romanian ranges — the accumulated result of address space acquired over decades rather than one clean allocation.
Notable
- A classic institutional network: a small, stable set of prefixes serving staff, students and research systems, with no subscriber pools and no hosting footprint.
- Romanian academic networks generally reach the wider research world through RoEduNet, the national research and education network, and university ASes like this one sit behind that fabric.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-17. 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.
