AS11911 THE-BANK-OF-NEW-YORK-MELLON-CORPORATION-AS11911

THE-BANK-OF-NEW-YORK-MELLON-CORPORATION-AS11911 is exactly what it says: an enterprise AS belonging to BNY Mellon, the custody and asset-servicing bank headquartered at 240 Greenwich Street in New York. ARIN has the ASN registered to the bank since 1999, with the record last updated in 2021. This is one of the cases where the famous-sounding name survives the check — the registry address and every prefix registrant point back to the same corporation.

What it's used for

RIS sees 52 IPv4 prefixes carrying about 90,880 addresses, no IPv6 in the observed window, and only 6 observed neighbours. That ratio is the tell: ninety thousand addresses reached through a handful of upstreams is a large enterprise, not a network with customers. A carrier of that address size would show peers by the hundred.

The inventory is anchored by two large legacy-style blocks, 170.61.0.0/17 and 160.254.0.0/17, plus dozens of /22–/24 carve-outs from 167.113.0.0 and 167.222.0.0. Every registrant sampled is BNY Mellon itself, under handles that include a distinctly internal one, BNY-BNY-EME-WOK — a site code rather than a product name. The space carries the bank's own global corporate estate: data centres, branch and office connectivity, and the internet edge for client-facing financial platforms.

Notable

None of the sampled addresses returned reverse DNS. That is a sample, not a finding, and no posture should be read into it — but it is unremarkable for a bank whose public surface is deliberately narrow relative to the size of its internal estate.
