AS6495 HSBC MEXICO SA INSTITUCION DE BANCA MULTIPLE GRUPO FINANCIERO HSBC

AS6495 is registered to HSBC México, S.A., Institución de Banca Múltiple, Grupo

Financiero HSBC — the Mexican banking arm of HSBC, with its registered address

on Paseo de la Reforma in Mexico City.

What it's used for

• The bank's own corporate and branch network: internal systems, customer-facing banking services, and the bank's public presence in Mexico.
• Announces around 3,500 IPv4 addresses out of 200.16.32.0/19 and adjacent LACNIC space.

Notable

• Reverse DNS for the address space is delegated to HSBC's own global nameservers (ns1.hsbc.us, ns20.hsbc.uk), which is the clearest signal that this is a bank running its own enterprise network rather than anything hosted or resold.
• This is one of the few low-numbered ASNs administered by LACNIC; it was transferred into the Latin American registry from the original ARIN-era records, and ARIN still lists the number as LACNIC-6495.

Interesting

• The ASN was registered in 1996 and the /19 in 1994, both predating HSBC's arrival in the Mexican market — the bank entered Mexico in 2002 through its acquisition of Grupo Financiero Bital, so the number and its address space were inherited rather than newly requested.
