Unclassified APNIC
Summary
SmarTone Telecommunications
isp mobile residential legacy
AS9474 (SMARTONE-AS-AP) is held by SmarTone Telecommunications Ltd., the Hong Kong mobile and broadband operator listed as SmarTone Telecommunications Holdings and majority-owned by Sun Hung Kai Properties. It carries SmarTone's own subscriber and service address space in Hong Kong, not third-party traffic.
What it's used for
The AS is a single contiguous block of legacy APNIC space: 17 IPv4 prefixes totalling 16,384 addresses, all inside 202.140.64.0/19 and 202.140.96.0/19, plus one IPv6 allocation, 2403:fa00::/32. The reverse DNS is the tell — nearly every sampled address resolves to a machine-generated PTR of the form m202-140-64-5.ismart.net, with a handful under smartone.com.hk. ismart.net is SmarTone's own operational domain (it is the domain on the network's published abuse contact), so this is customer- and service-facing address space handed out under a uniform naming scheme rather than a block leased out to other parties.
With only one observed BGP neighbour, AS9474 is not a transit network. It sits behind a single upstream and exists to originate SmarTone's own prefixes. That shape (a modest, dense address holding, uniform operator-controlled rDNS, near-zero peering) is the classic signature of an access network serving its own users, not a wholesale carrier.
Notable
- SmarTone runs more than one AS; the mobile side is routed separately under AS17924. Card the network in front of you: AS9474 is the older
202.140/19holding. - The address count is small for a national operator, which is normal for a Hong Kong carrier that leans on carrier-grade NAT and IPv6.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
