Residential RIPE
Summary
LG HelloVision Corp.
isp residential legacy
AS9845 (CJCKN-AS-KR) is held by LG HelloVision Corp., South Korea's largest cable operator and a subsidiary of LG Uplus. The company was previously CJ HelloVision / CJ Hello, and the CJCKN handle preserves that lineage; LG Uplus acquired it and the company took its current name in December 2019. LG HelloVision runs digital cable TV alongside a substantial high-speed internet access business.
What it's used for
The routing evidence is that of a real eyeball network. RIS sees 316 IPv4 prefixes carrying roughly 302,848 addresses, and only three BGP neighbours. That ratio is the point: 300,000 addresses is a large subscriber-scale pool, but three neighbours means the AS sells nothing upstream and has essentially no customer cone. A wholesale carrier with that much space would peer with hundreds of networks. A big address count with almost no neighbours is an access network serving its own users, which is exactly what a cable ISP looks like.
The prefixes back this up. They are dominated by /21s drawn from a handful of contiguous Korean ranges (110.44.0.0, 110.46.0.0, 113.130.0.0, 180.182.0.0, 61.110.0.0), deaggregated into hundreds of small announcements. Splitting large residential pools into per-region /21s and /24s is standard practice for a cable operator carrying subscribers across many local franchise areas.
Notable
- No IPv6 is announced by this AS in RIS, despite its size, so the residential estate here is IPv4-only as far as the global table is concerned.
- The handle still says
CJ, and the holder is now LG. The name on an AS is not evidence of who runs it.

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.
