Summary

Banco de España

Spain · AI-generated

government financial infrastructure

BANCOESPANAAS is operated by Banco de España, the central bank of Spain.

What it's used for

  • The address space carries internal banking infrastructure, evidenced by netnames ES-BDE-20070326 and BANCO_ESPANA associated with the registrant Banco de España.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • Registrants align with the announcer for the primary block, while the secondary block 217.124.152.0/24 lists NEMESYS ABUSE TEAM as the registrant, suggesting a specific operational or abuse-handling segment within the estate.
  • The inventory consists of two distinct IPv4 blocks and two IPv6 prefixes, reflecting a finely subdivided internal corporate estate typical of a central bank's segregated network architecture.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
