Summary
VDC Powerbase Hong Kong Data Centers (Vantage)
hosting legacy
AS9925 (HKTDCS-AS-AP) is held by VDC Powerbase Hong Kong Data Centers Limited. The network began life as PCCW's data-centre arm, PCCW Powerbase Data Center Services (HK), and passed to Vantage Data Centers when DigitalBridge acquired PCCW's Hong Kong and Malaysia data-centre business for $750m, a deal that closed in December 2021. Several routing databases still carry the old PCCW Powerbase name, which is the usual lag after a corporate transfer.
What it's used for
Colocation and data-centre connectivity. RIS sees 35 IPv4 prefixes carrying 76,032 addresses, one IPv6 prefix (2401:9f00::/32), and 7 observed BGP neighbours. That combination is the classic hosting shape: a substantial address pool — far more than any enterprise needs for itself — but a very small peering fabric, because a colocation operator's job is to hand addresses and rack space to tenants, not to sell transit to other networks or to serve eyeballs.
The inventory backs that up. The space is drawn from many separate APNIC parents (202.77, 202.85, 202.123, 202.153, 203.86, 203.105, 203.161, 203.215) and includes real aggregates — a /18, several /19s and /20s — rather than a scatter of unrelated /24s. That is address space accumulated over two decades of running Hong Kong facilities, then subdivided per customer, which is exactly what you would expect of an operator whose lineage runs back to a national incumbent.
Notable
- The handle
HKTDCSpredates both current names and is a fossil of the network's telco-incumbent origin. - Attribution against this ASN identifies a facility, not a service. Whatever a tenant is running lives behind these addresses; the ASN tells you only where the racks are.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,775 prefixes, as published 2026-10-11. 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.
