About this network
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.com PTRs are direct evidence of an OpenStack-based IaaS platform living in this AS.
