Summary
Hong Kong Cable Television (i-CABLE)
isp residential legacy
AS9513 (HKCABLE-HK-AP) is held by HK Cable TV Ltd — Hong Kong Cable Television Limited, the cable operator that trades as i-CABLE. It is one of Hong Kong's long-established hybrid TV-and-broadband carriers.
What it's used for
This is an access network. RIS sees 11 IPv4 prefixes covering 17,408 addresses, no IPv6, and a single observed BGP neighbour. The rDNS is the giveaway and it is unusually clean: every sampled address answers with a mechanical ipNNNNNN.hkicable.com name derived from the last two octets — 203.83.64.5 becomes ip064005.hkicable.com, 203.168.132.5 becomes ip132005.hkicable.com. Generated per-address PTRs on that pattern are what a subscriber-access pool looks like: the operator delegates a name to every customer IP whether or not anyone uses it. The holdings are correspondingly tidy — a 203.83.64.0/18 with its two halves deaggregated, plus 203.168.132.0/22 and a handful of longer specifics carved out of the same space, i.e. one contiguous allocation traffic-engineered rather than a scattered inventory.
Notable
- The single observed neighbour marks this as a transit customer, not a peer-heavy carrier. The address count is modest for a consumer ISP, so this AS is likely one slice of i-CABLE's routing rather than its whole subscriber base.
- i-CABLE also appears in the table under a sibling registration, AS9908, also registered as HK Cable TV Ltd.
- The company was formerly Wharf Cable Television and has since passed into different ownership; the AS and its
203.83.0.0space have stayed with the network through those changes.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
