Summary

UBS Group (former Credit Suisse network)

Switzerland · AI-generated

enterprise finance legacy

Credit Suisse Group — the AS is still registered under that handle, but the holder is now UBS Group AG, which absorbed Credit Suisse in the 2023 rescue merger. Roughly 4,800 IPv4 addresses across ARIN blocks in 198.240.0.0/16 and 199.53.0.0/16, plus two IPv6 /48s.

What it's used for

  • Corporate and internet-facing infrastructure for a global investment bank. The rDNS is still entirely credit-suisse.com and credit-suisse.ch: web and mail gateways, the Directnet online-banking front end, careers and client portals.
  • Two BGP neighbours and no customer space beneath it. This is enterprise edge routing, not a service-provider network.

Notable

  • The handle outlived the bank. Anything keyed on the AS name will file this as Credit Suisse; anything keyed on the registry will file it as UBS. Both are describing the same infrastructure, mid-migration, with the old brand still on every hostname.
  • A bank's own AS is a small, deliberately boring thing: a couple of thousand addresses of public-facing gateways. The trading and back-office estate sits behind it on private space, not in the AS.

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 1,779 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.
