Summary
UBS Group AG
UBSGROUPAG-AS-AP belongs to UBS Group AG, the Swiss global bank. This is a corporate enterprise AS: the bank routing its own offices, trading floors and data centres, with no product sold over it.
What it's used for
UBS's internal and internet-facing corporate network. The AS announces 71 IPv4 prefixes totalling 13,824 addresses plus 6 IPv6 prefixes. The shape of the announcement is the giveaway — almost every prefix is a /23, carved out of a handful of large legacy blocks (138.206.0.0/16, 147.60.0.0/16) plus APNIC space in 202.1.0.0/16. A bank subnets its estate that way: one /23 per site, per campus or per security zone, each announced separately so it can be steered independently. An ISP does not build a routing table out of seventy near-identical /23s.
Notable
This is an enterprise network, not a carrier or a hosting provider. Roughly 13,800 addresses against just 15 observed BGP neighbours is the classic corporate silhouette: a couple of transit providers in each region and nothing else. A wholesale carrier at this size would peer with hundreds of ASes. The -AP suffix on the handle records only that the number was issued by APNIC for UBS's Asia-Pacific operations; the same AS carries the bank's European and North American legacy space.
Interesting
Address space registered to a bank is normally staff and back-office space, so it should be geolocated to UBS premises rather than to customers. Treat traffic from it as originating with the institution itself.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
11 upstream, 1 downstream and 17 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
