About this network

AS9319 (HCNCHUNGJU-AS-KR) is held by HCN Chungbuk Cable TV Systems, the North Chungcheong regional arm of the Korean cable operator HCN (formerly Hyundai HCN). Registry contacts place it in Cheongju, Chungcheongbuk-do, and use a kthcn.co.kr address, reflecting the operator's absorption into the KT group.

What it's used for

This is a cable broadband eyeball network, and the routing evidence says so plainly. RIS sees 202 IPv4 prefixes carrying 93,696 addresses with no IPv6, announced through just 1 observed BGP neighbour. A single upstream and ninety-odd thousand addresses is the exact opposite of a transit operator's profile: everything here is subscriber space, backhauled to one carrier.

The prefix list is the other tell. Apart from a single 112.72.128.0/17, the announcements are almost entirely /22s — dozens of them, scattered across 112.72.x, 49.143.x, 111.118.x and 27.35.x. That fragmentation into uniform small blocks is what a cable operator's regional headend allocations look like: address space handed out in fixed-size chunks per serving area as the network grew, rather than the aggregated blocks a carrier would announce.

Notable

• Korean cable operators historically registered one ASN per regional franchise, which is why a single province's cable TV system holds its own low-numbered AS.
• The network carries broadband subscribers of a cable television franchise, so the eyeballs here are residential rather than business.
• No IPv6 is announced.
