Summary
Barclays Bank PLC
banking corporate internal uk
BARCLAYS-RETAIL is the autonomous system for Barclays Bank PLC.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by netnames such as
BARCLAYS-CIBWM,BARCLAYS-SINGAPORE, andBARCLAYS-RBB. - The AS announces 12,032 IPv4 addresses across 10 prefixes with only 4 observed neighbours, indicating a small, internal corporate estate rather than a transit or access network.
- Traffic from this AS consists of internal banking operations, including corporate and investment banking systems and regional office backhaul.
Notable
- All registrants are listed as unknown in the RDAP data, but the netnames consistently identify Barclays entities.
- The inventory is finely subdivided into specific business units and geographic locations, such as Singapore and CIBWM, reflecting site-by-site segmentation of the corporate network.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-24, 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.
