About this network

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 203.83.0.0 space have stayed with the network through those changes.
