Summary
kt HCN (formerly Hyundai HCN)
isp residential legacy
AS9762 (HCN-AS) is held by kt HCN Co., Ltd. — the cable multiple-system operator formerly known as Hyundai HCN (Hyundai Communications Network), which is the name the older registry records and the ASN handle still carry. KT Skylife was named preferred bidder for Hyundai HCN's broadcasting business in 2020 and completed the acquisition in September 2021, after which the company was rebranded under the KT banner.
What it's used for
This is cable broadband access space. RIS shows 76,800 IPv4 addresses spread across 111 prefixes, and the distribution is the giveaway: after a /20 and a few /21s, the bulk of the announcements are /22s scattered across a dozen unrelated address ranges — 49.142.x, 120.50.x, 202.150.x, 123.108.x, 114.199.x, 110.35.x, 211.47.x and more. Non-contiguous space in small uniform blocks is what a cable MSO accumulates as it wires up separate franchise areas, each headend getting its own allocation over the years. Against those 76k addresses there is just one observed BGP neighbour, which rules out any wholesale or transit role. It is an eyeball network hanging off a single upstream — now, in practice, its parent. No IPv6 is announced from this ASN.
Notable
- The Korean cable sector consolidated almost entirely into the mobile carriers. HCN went to KT, CJ HelloVision to LG Uplus (see AS9770), t-broad to SK Broadband.
- Regulators granted the KT Skylife takeover only conditionally, with pricing and channel-count restrictions attached.

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: 442 networks and 1,773 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.
