About this network

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.
