AS6773 Rua Soeiro Pereira Gomes, Lote 1

SIBS Forward Payment Solutions, S.A. is Portugal's interbank payment services

company, owned by the Portuguese banks and best known for running the Multibanco

ATM and card network and the MB WAY mobile payments service.

What it's used for

• The corporate and payments-processing network of SIBS itself. The announced space is a contiguous run of prefixes out of 195.138.0.0/21 and neighbouring /24s, all registered under the netname SIBS.
• No subscriber or hosting reverse DNS appears in the space: this is a financial institution's own network, not a service sold to third parties.

Notable

• Registry records still carry the company's former name, SIBS Sociedade Interbancaria de Servicos, and its old Lisbon address on Rua Soeiro Pereira Gomes, while the organisation record uses the current name and its Amadora headquarters. Automated ASN lists that read the wrong field sometimes end up showing a street address as the operator's name.
• Multibanco is one of the most heavily used national payment networks in Europe relative to population, which puts a payments processor behind an early ASN that most people will never knowingly connect to.
