Summary
Wells Fargo Bank, N.A.
enterprise legacy
WELLSFARGO-10837 is registered to Wells Fargo Bank, N.A., the US retail and commercial bank. It is one of several ASNs the bank operates, and it carries the bank's own network rather than any customer-facing service business.
What it's used for
Corporate connectivity for a large regulated enterprise. RIS sees 84 announced IPv4 prefixes carrying roughly 66,560 addresses, plus two IPv6 /44s (2620:160:e700::/44 and 2620:160:eb00::/44), against only 3 observed BGP neighbours.
That ratio is the whole story. Eighty-four prefixes with barely a handful of BGP peers is not an eyeball or transit network; it is an enterprise that multihomes to a small number of upstream carriers and deaggregates heavily inside its own space. The prefix list bears this out: three /19-sized parents — 151.151.0.0, 159.45.0.0 and 162.29.64.0 — sliced into a long series of /22s. Splitting a contiguous allocation into uniform /22s is how an organisation with many sites and data centres steers traffic between its own entry points, not how an ISP hands addresses to customers.
Notable
The 2620: IPv6 prefixes are ARIN direct assignments from the block set aside for US organisations taking provider-independent space, which is what a bank with strict change-control and multi-carrier requirements would take rather than depend on a single upstream's addressing.
No reverse DNS was returned for the addresses sampled here. That is a sample, not a finding, and no conclusion is drawn from it.

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 1,783 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.
