About this network

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.
