Summary
CBlue
business isp belgium managed
CBLUE-AS is operated by CBlue SPRL, a Belgian internet service provider and managed services company based in Namur.
What it's used for
- The address space carries corporate and managed service infrastructure, evidenced by netnames such as
FR-CBLUE-20190222,BE-CBLUE-20130919, andCBLUE-NET1, alongside leased space from Venn SA (BE-VENN-20170330,VENN-Managed_183). - With 3,584 IPv4 addresses announced across 5 prefixes and only 3 observed neighbours, the network functions as a small-scale access or business provider rather than a transit hub.
- Traffic from this AS consists of business clients, managed services, and internal corporate endpoints, consistent with CBlue's role as a local ISP and IT service provider.
Notable
- Registrants are consistent with the announcer, listing CBlue SPRL for most prefixes, while two prefixes are registered to Venn SA, indicating leased or managed address space.
- The address inventory is modest and fragmented, with a mix of /22 and /24 blocks, reflecting a small regional operator with specific site or client allocations.

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 2026-10-28, 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
