Summary

Barclays Bank PLC

Italy · AI-generated

banking corporate italy

BARCLAYS-ITALY-NET is operated by Barclays Bank PLC.

What it's used for

  • The space carries corporate banking infrastructure, identified by the netname BARCLAYS-ITALY-NET and registrant Barclays Bank PLC.
  • The AS announces 512 IPv4 addresses across 1 prefix (195.191.84.0/23) with 2 observed neighbours, indicating a small, self-contained internal corporate estate rather than a transit or access network.
  • Traffic consists of internal office workers, branch backhaul, and web/API endpoints for Barclays' Italian banking operations.

Notable

  • The registrant Barclays Bank PLC matches the AS handle and announced prefix owner.
  • The address inventory is a single contiguous /23 block, typical of a dedicated corporate allocation for a specific geographic entity.

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 1,784 prefixes, as published 2026-10-19. 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.
