business hk it
ABCHK-HK is the autonomous system for ABC Computer Systems Ltd.
What it's used for
- The address space is registered under the netname
ABCHK-HKforABC Computer Systems Ltd, indicating a corporate IT infrastructure estate. - The AS announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio consistent with a single-site or small-scale business network rather than a transit or large access provider.
- Traffic from this AS consists of internal corporate endpoints and IT services for the company's operations in Hong Kong.
Notable
- Registrants for both announced prefixes match the AS holder,
ABC Computer Systems Ltd. - The address inventory is compact, comprising two contiguous IPv4 blocks in the 223.29.248.0/23 and 223.29.250.0/24 range.

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 1,784 prefixes, as published 2026-10-19. 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.
