Summary

Caixa Geral de Depósitos

Portugal · AI-generated

business banking corporate

The AS handle CGDNET is held by Caixa Geral de Depósitos, SA.

What it's used for

  • The address space carries corporate infrastructure for a major Portuguese bank, evidenced by the netname CGDNET and registrant CAIXA GERAL DE DEPOSITOS, SA on 195.234.134.0/24.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 3 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.

Notable

  • Registrants do not fully agree with the announcer; 193.126.115.0/24 is registered to NOS COMUNICACOES, S.A. with netname PT-NOS-19950609, while 195.234.134.0/24 is registered to CAIXA GERAL DE DEPOSITOS, SA.
  • The inventory is split between a bank-owned prefix and a prefix registered to a telecommunications operator, suggesting a specific arrangement for that address block.
  • Reverse DNS for the NOS-registered prefix points to net.novis.pt, indicating the space is used for network services.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
