Summary
Isabel Group
enterprise finance legacy
The corporate Autonomous System of Isabel N.V. (ISABEL), the Brussels-based Belgian fintech behind the Isabel 6 multibanking platform. Isabel sits between Belgian companies, accounting firms and hundreds of European banks, and operates under the supervision of the National Bank of Belgium.
What it's used for
- Isabel's own platform infrastructure: the multibanking and payment-initiation services, e-invoicing and document-exchange products, and the secure links it maintains to its partner banks.
- The announced space is one coherent range (
195.122.96.0/20, carved into many /24s) plus a couple of extras, registered with the netnameISA-NETin Brussels. That is an enterprise inventory, not a provider's.
Notable
- Financial-sector enterprise space. These addresses belong to Isabel and its platform, not to customers. There are no subscriber or hosting pools, and almost no public reverse DNS is published on the block.
- Very few observed BGP neighbours: the company multi-homes to a small set of upstreams, the normal posture for a regulated financial-infrastructure operator that wants resilience rather than reach.
- The heavy carve into individual /24s is characteristic of a network that segregates per-service and per-partner connectivity rather than running one flat block.

Interconnection
Peering at a glance
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 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
