Summary
HCN Kumho Broadcasting (Geumho Cable)
residential cable isp south-korea
HCNKUMHO-AS-KR is the network of HCN Kumho (Geumho) Broadcasting, one of the regional cable system operators in the HCN group. Korean cable SOs sell cable TV and broadband to households in a licensed franchise area, and that is what this AS carries.
What it's used for
- Cable broadband and cable-TV subscriber access for homes in the operator's regional franchise, plus the operator's own head-end and back-office systems.
Notable
- The kind is residential (eyeball), and the shape of the routing is the argument. RIS observes 51 IPv4 prefixes and 46,080 addresses behind a single neighbour. That combination is decisive: a wholesale carrier holding ~46k addresses would be peering with hundreds of ASes, because selling transit is the whole business. One upstream and forty-six thousand addresses is a network that consumes transit on behalf of a lot of end users.
- The prefixes reinforce it. They are the classic Korean eyeball mix drawn from many different KRNIC ranges (
114.199.192.0/19,110.35.192.0/19,27.35.96.0/20,49.143.96.0/20,111.118.96.0/20and dozens of/22s), i.e. address space accumulated piecemeal as the subscriber base grew, then deaggregated to steer traffic across the franchise.
Interesting
- HCN was a Hyundai Department Store Group cable business; its controlling stake passed to KT Skylife in 2021, so this regional network now sits inside the KT orbit while keeping its own ASN and address space.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
