Summary
KoçSistem Bilgi ve İletişim Hizmetleri A.Ş.
enterprise hosting legacy
KOCSISTEM is KoçSistem, the information-technology and managed-services company of Turkey's Koç Holding conglomerate. It provides IT integration, data-centre, cloud and managed-connectivity services to enterprise clients.
What it's used for
The AS announces 13 /24s (about 3,328 addresses) with two observed BGP neighbours. The space hosts and connects enterprise workloads for KoçSistem's customers rather than serving broadband subscribers.
Notable
Reverse DNS lands on the hostnames of the enterprises it serves: mx1.otokar.com.tr (Otokar, a Koç-group vehicle maker), portal.tofas.com.tr (Tofaş, the Fiat joint venture) and mx3.chippin.com.tr. Mail and portal servers for third-party corporates are the signature of a managed-IT/hosting provider, not a single-company enterprise network.

Internet exchanges
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 2026-11-03, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
