AS8883 Switzerland
Unclassified RIPE
Summary
UBS AG
enterprise finance legacy
AS8883 is registered to UBS AG, the Swiss global bank. Some ASN listings show this network's name simply as "Switzerland" — that is a field from the registry object, not the operator's identity. The holder is the bank.
What it's used for
UBS's own global corporate network. RIS observes about 8,960 IPv4 addresses spread across 52 prefixes, plus a dozen IPv6 prefixes, behind only five neighbours. That combination — many small prefixes, very few upstreams — is the classic multinational-enterprise shape: office and data-centre blocks in several countries, each announced separately, all homed to a handful of carriers under contract.
No PTRs came back on the addresses sampled. That is not evidence of an undelegated zone, and for a bank it is unremarkable either way: financial institutions routinely keep reverse DNS sparse or internal on their own space.
Notable
- The inventory mixes ARIN-era legacy blocks (
155.145.0.0/16fragments,165.222.0.0/16fragments,156.115.x) with RIPE space (193.134.x,193.5.106.0/24). The155.145and165.222ranges are inherited from the pre-merger US operations of the Swiss banking groups that became UBS. - Scattered small prefixes across multiple RIRs superficially resembles the address-broker silhouette, but every block here is registered to UBS itself. It is a real, if untidy, enterprise network.
- Classified
business. Despite the size and geographic spread, nothing in this AS is sold to anyone: no transit, no hosting, no subscriber pools.

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 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
