Summary
LG HelloVision (Gayanet)
GAYANET-AS-KR is held by LG HelloVision Corp., South Korea's largest cable-TV multiple system operator. The GAYANET name is inherited from one of the regional cable system operators the group absorbed as it consolidated — LG HelloVision runs more than twenty SOs across some two dozen franchise areas, clustered around Seoul and Busan, and each brought its own network and address space with it.
What it's used for
Consumer broadband over cable, sold with digital TV and telephone. The AS announces 85 IPv4 prefixes totalling 139,520 addresses and no IPv6, and the composition is unambiguous: page after page of /21s from 110.45.0.0, 115.41.0.0, 119.149.0.0 and 123.199.0.0. Uniform /21s repeated eighty-odd times is subscriber-pool geometry — one block per headend or CMTS — not the ragged, purpose-built layout of an enterprise or the dense mixed sizes of a hosting platform. 139,520 addresses only make sense if there are households on the far end of them.
Notable
An eyeball network, and the neighbour count settles it beyond the name. Nearly 140,000 addresses with exactly one observed BGP neighbour describes a regional access ISP that single-homes into its parent's national backbone and sells transit to nobody. A wholesale carrier holding this much space would show hundreds of adjacencies. LG HelloVision is majority-owned by LG Uplus, one of Korea's three national telcos, which is very likely what that single adjacency is.
Interesting
Cable broadband is now a small minority of Korean internet access, surviving mainly where older hybrid fibre-coaxial plant has not yet been replaced with fibre. Compare AS10054, CMB Kwangju — the same business in a single region.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
