Summary
Cegeka NV
hosting enterprise legacy
AS9166 (CEGEKA-HASSELT) is held by Cegeka NV, a Belgian IT services and managed-hosting group headquartered in Hasselt. The handle names the city, and the AS carries Cegeka's own data-centre and cloud estate rather than a consumer access network.
What it's used for
RIS sees 14 IPv4 prefixes covering 13,824 addresses and 9 IPv6 prefixes, against only 3 observed BGP neighbours. That combination is the signature of an enterprise hosting provider: enough address space to number a substantial multi-tenant estate, but a peering footprint of essentially just its upstreams. A wholesale carrier with this much space would have hundreds of neighbours; a provider that buys transit and serves its own racks has three.
The address space is a mix of older PA blocks (212.113.64.0/19, 62.233.0.0/20) and a cluster of 194.53.13x.0/24s, each announced both as an aggregate and as its component /23s and /24s. The IPv6 side is notably well-developed: nine prefixes across 2a02:2398::/xx, 2a02:2399::/xx and 2a02:239c::/48, which is more dual-stack investment than a network this size usually bothers with.
Reverse DNS confirms the role. 212.113.64.5 is dnsmaster.cegeka.be and 212.113.72.5 is unknown.openstack.cegeka.com — the latter is the auto-generated PTR pattern of an OpenStack cloud, i.e. tenant VM addresses in Cegeka's own private-cloud platform.
Notable
- Cegeka runs data centres in Hasselt and in Geleen, the Netherlands, and its offering is multi-cloud, outsourcing and managed infrastructure.
- The
openstack.cegeka.comPTRs are direct evidence of an OpenStack-based IaaS platform living in this AS.

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 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
