business enterprise finance banking

WELLSFARGO-10372-10376 is Wells Fargo Bank, N.A. The handle covers a block of ASNs registered together; this is the sibling of AS10372, and both announce the bank's own space.

What it's used for

  • Bank infrastructure: data-centre and office connectivity, internal systems and internet egress for a national retail and commercial bank. Running several ASNs lets the bank route different sites or business functions independently of one another.
  • The space is drawn from several blocks — the 168.175.132.0/22 and 168.175.136.0/22 pair, the 199.230.96.0 range, 204.86.136.0/22 and 204.86.144.0/22, and a run of 171.72.x.0/24s — the accumulated allocations of a decades-old enterprise IT estate.

Notable

  • Enterprise, not carrier or hosting. RIS sees 25 IPv4 prefixes / 9,216 addresses announced with 9 observed BGP neighbours. Nine thousand addresses is a small footprint, and nine neighbours is the number of transit relationships a large corporate buys for redundancy — not a customer cone. A wholesale carrier at any address scale peers with hundreds of ASes.
  • Note the contrast with its sibling AS10372, which announces more space (24,576 addresses) through fewer neighbours (6). Two ASNs held by one organisation with different address volumes and different upstream counts is deliberate separation of routing domains.

Interesting

  • Banks are among the most conservative BGP operators on the internet: heavily deaggregated, multiply-homed, and slow to renumber. Every prefix here is a /22 or longer, which keeps failover granular at the cost of a larger routing table.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
