Unclassified APNIC
Summary
Cathay Pacific Airways
enterprise legacy
The corporate network of Cathay Pacific Airways (CATHAYPACIFIC-AS-AP), Hong Kong's flag carrier airline.
What it's used for
- Enterprise networking for an airline: corporate offices, the Hong Kong headquarters, and the IT systems behind reservations, operations, and cargo.
- Public-facing Cathay Pacific services reachable from this address space.
Notable
- An airline is an unusual thing to find at the bottom of the AS number space. Cathay is an enterprise holder, not a service provider: the addresses serve the company itself rather than paying subscribers.
- Registered through APNIC in Hong Kong, which puts it among the earlier commercial allocations in the region.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
