Unclassified RIPE
Summary
Worldline Financial Services (Europe) S.A.
enterprise legacy
The Luxembourg network of Worldline Financial Services (Europe) S.A., still registered under the handle CETREL-LU-AS1 from its origin as Cetrel S.A., the country's long-standing card and payment processor.
What it's used for
- Corporate and payment-processing infrastructure for Worldline's Luxembourg operations, including services for banks and merchants.
Notable
- Financial-industry address space rather than an ISP or hosting network. Traffic here is a payments processor's own systems and the interfaces its bank and merchant customers connect to.
- Cetrel was absorbed into SIX Payment Services and then into Worldline, which is why the RIR handle still carries the old Cetrel name while the holder is Worldline.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
