Summary
Groupement des Cartes Bancaires (GIE CB)
enterprise finance legacy
GIECB is the Groupement des cartes bancaires CB, the French interbank economic-interest grouping (GIE) that governs the "CB" bank-card network shared by France's major banks.
What it's used for
The AS announces a single 193.104.39.0/24, whose sampled reverse DNS resolves under rev.e-rsb.com (the interbank Réseau de Services Bancaires). This is dedicated financial-network infrastructure for card authorisation and interbank messaging, not a public ISP.
Notable
- The CB grouping is the scheme behind the physical "CB" cards carried by essentially every French current account, co-processing transactions alongside Visa and Mastercard.
- A one-
/24, two-neighbour footprint is exactly what a private financial-sector AS looks like: minimal public routing, purpose-built for a closed application.

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 1,778 prefixes, as published 2026-10-20. 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.
