About this network

A Portuguese bank whose blocks are numbered 01, 02 and 03 instead of dated, plus one belonging to a telco.

What it's used for

• Banking connectivity. 1,280 addresses in four IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• Three blocks are netnamed PT-SERVIBANCA-01, PT-SERVIBANCA-02 and PT-SERVIBANCA-03, all registered to Millennium BCP-Prestacao de Servicos ACE.
• The fourth, 88.157.230.0/23, is PT-NOS-20060125, registered to NOS Comunicacoes with its own admin, tech and abuse contacts.
• One of the bank's blocks is 66.33.88.0/24, from a range administered on the other side of the Atlantic, yet numbered into the same SERVIBANCA sequence as the European ones.

Interesting

• Sequence numbers instead of dates is the older habit, and the more useful one for anyone reading the records later. -01, -02, -03 says these blocks belong together and in what order they were taken; a date only says when.
• SERVIBANCA names the shared banking-services operation rather than the bank, and ACE is the Portuguese legal form for a consortium — several banks pooling an operation into one entity. The netname records the joint venture that runs the network, not the brand on the branch door.
• A telco's block inside a bank's AS is the ordinary arrangement where connectivity is bought as a service. NOS keeps the registration and its own abuse contact; the bank announces it.
