Summary

The Hongkong and Shanghai Banking Corporation (HSBC Hong Kong)

Hong Kong · AI-generated

enterprise legacy

AS9221 (HSBC-HK-AS) is held by The Hongkong and Shanghai Banking Corporation Limited, the Hong Kong arm of the HSBC banking group. It is a corporate network: HSBC's own Internet-facing address space in Hong Kong, not a service sold to anyone else.

What it's used for

The routing evidence is textbook enterprise. RIS sees 33 IPv4 prefixes carrying 14,336 addresses, plus 6 IPv6 prefixes, and only 9 BGP neighbours. That ratio is the giveaway: a wholesale carrier of this size would peer with hundreds of networks, and an eyeball ISP with this much space would show many more upstreams and exchange sessions. Nine neighbours on a modest, tightly clustered address footprint is what a large multinational buys when it wants multihomed, provider-independent connectivity for its own premises and its own public services.

The space itself is concentrated in three ranges — a 161.113.192.0/19 and blocks in 203.112.80.0/21 and 27.110.72.0/21 — and it is heavily deaggregated, with most of the announcement list made up of /23s carved out of those parents. Splitting a /19 into /23s is standard practice for a bank steering traffic between data centres and for keeping specific service blocks pinned to specific upstreams.

Notable

  • The 2406:0dc0:: IPv6 prefixes are APNIC-region assignments, consistent with a Hong Kong-registered holder rather than an inherited European or American allocation.
  • HSBC runs separate autonomous systems in other regions; this one is the Hong Kong entity's network and should not be read as covering the whole group.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
