Summary
Wells Fargo Bank
enterprise legacy
Autonomous System 4243 (WELLSFARGO-4243) is registered to Wells Fargo Bank, N.A.,
one of the largest banks in the United States.
What it's used for
- Corporate network connectivity for Wells Fargo's own infrastructure. The AS announces only a small amount of address space, so it is one edge of a much larger internal network rather than the whole of it.
Notable
- Institutional address space: bank staff and bank systems, not retail customers.
- Wells Fargo holds several AS numbers. Banks of this size multihome across multiple carriers and split routing across ASNs for resilience and separation.
- The AS number dates from the mid-1990s, when large enterprises were among the first non-academic organisations to run BGP of their own.
