Summary

Millennium BCP

Portugal · AI-generated

finance enterprise

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.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
