Summary
Wells Fargo Bank
business enterprise finance banking
WELLSFARGO-10372-10376 is Wells Fargo Bank, N.A., one of the largest US banks. The handle names a range of ASNs — this AS and AS10376 are registered together and both carry the bank's own network.
What it's used for
- Corporate and retail banking infrastructure: branch and office connectivity, data centres, internal applications, and the internet-facing edge of a bank with thousands of physical locations.
- The address space is a mixture of legacy
151.151.96.0/20and159.37.0.0blocks with newer162.28.0.0and162.60.0.0ranges — a long-lived enterprise that has accumulated allocations over decades rather than acquired them recently.
Notable
- Enterprise, and the shape is textbook. RIS sees 73 IPv4 prefixes / 24,576 addresses announced with only 6 observed BGP neighbours. The ratio is the tell: 73 prefixes is a lot of announcements, but they carve up a modest 24k of address space reached through six upstreams. A carrier with a customer cone would peer with hundreds of ASes; this network peers with the handful of transit providers a bank contracts with, and originates only its own space.
- Heavy deaggregation into
/22s and/23s is how a geographically dispersed enterprise steers traffic between multiple data centres and egress points.
Interesting
- Financial institutions of this size deliberately split their public networking across several ASNs, which is why a single handle spans 10372 through 10376: it isolates failure domains and lets different business units or regions be routed independently.

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 2026-10-19, 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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
