Summary

Bilbao Bizkaia Kutxa

Spain · AI-generated

business finance corporate

BBK is the autonomous system for Bilbao Bizkaia Kutxa, a Spanish banking foundation.

What it's used for

  • The address space carries static client connections, as evidenced by reverse DNS entries like 64.212-142-161.static.clientes.euskaltel.es.
  • The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, isolated corporate network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant for the announced prefix is EUSKALTEL RIPE, which differs from the AS holder BBK Bilbao Bizkaia Kutxa, suggesting the address space is leased or managed by Euskaltel on behalf of the bank.
  • Bilbao Bizkaia Kutxa was transformed into a banking foundation in 2014, transitioning from its previous status as a savings bank.
  • The inventory consists of a single /24 block (212.142.161.0/24) with no IPv6 prefixes, reflecting a minimal and specific corporate footprint.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
