Summary

Coutts & Co AG

Switzerland · AI-generated

banking corporate private-bank

RBS-SERVICES-LTD is the AS handle for Coutts & Co AG, a Swiss private bank.

What it's used for

  • The space carries corporate banking infrastructure, evidenced by the netname RBS-COUTTS-BANK-LTD and registrant Coutts & Co AG.
  • The AS announces 512 IPv4 addresses within a single prefix (193.8.50.0/23) and maintains 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal bank operations, employee access, and secure financial services endpoints for Coutts' private and commercial banking clients.

Notable

  • Registrants align with the announcer, listing Coutts & Co AG and RBS-Services-NOC for the sole announced prefix.
  • The address inventory is compact, consisting of a single /23 block, which fits the profile of a dedicated corporate network for a specific business unit.

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 2026-11-01. 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.
