About this network

BOCI-HK-AP belongs to BOC International Holdings Limited, the Hong Kong-based investment-banking and securities arm of Bank of China. BOCI runs brokerage, asset management, futures and corporate-finance businesses out of Hong Kong.

What it's used for

• The firm's own internet edge: mail gateways, the client-facing trading and research portals, and the links between its Hong Kong offices and the wider Bank of China group.

Notable

The reverse DNS and the routing agree that this is an enterprise network. The one PTR in the sample is mailgw03e.bocigroup.com — a numbered corporate mail gateway in the holder's own domain. That is first-party infrastructure: it tells you the space carries BOCI's own services, not a customer base.

The topology says the same. RIS observes 2 announced IPv4 prefixes totalling 512 addresses (202.128.104.0/24 and 202.128.105.0/24, an adjacent pair), no IPv6, and 2 observed neighbours. Two upstreams and a /23-worth of addresses is the standard dual-homed corporate edge — announce your own space so you are not tied to a carrier's addresses, buy transit from two of them so one outage is not an outage. Anything selling connectivity would peer with far more than two ASes, and any eyeball network would need vastly more than 512 addresses.

Interesting

The -HK-AP handle and the APNIC-range prefixes place this firmly in Hong Kong, not mainland China: BOCI is the group's offshore investment bank, licensed and regulated by the SFC, and its network edge lives where its regulator does.
