Summary
Boğaziçi University
education university research legacy
Boğaziçi University (ASBOUN) — one of Turkey's leading public research universities, on the European shore of the Bosphorus in Istanbul.
What it's used for
- Campus networking: faculty and student systems, labs, libraries and university services. Sampled addresses resolve under
cc.boun.edu.tr, the university's computer centre domain. - Roughly 10,000 IPv4 addresses, most of it the classic
193.140.192.0/19-area academic assignment that Turkish universities were numbered from.
Notable
- Institutional address space: users here are students, staff and researchers on a campus network, not broadband subscribers. It should not be geolocated as consumer ISP space.
- The AS has very few BGP neighbours because Turkish universities reach the internet through the national research network rather than buying commercial transit directly.
Interesting
- Boğaziçi traces back to Robert College, founded in 1863, and its computer centre was one of the early nodes of Turkish academic networking — which is consistent with an AS number in this low, mid-1990s range.

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 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
