Summary
HCN
cable broadband residential korea
HYROADPUSAN-AS-KR is operated by HCN, a major South Korean cable television and broadband provider.
What it's used for
- The address space carries residential broadband and cable TV services, evidenced by netnames such as
HCN-KR,broadNnet-KR,SEJONG-KR, andBORANET-KR. - With 86,784 IPv4 addresses announced across 103 prefixes and only 1 observed neighbour, the high address-to-neighbour ratio indicates an access/eyeball network rather than a transit provider.
Notable
- Registrants for the largest prefixes are listed as
IRT-KRNIC-KR, which is the Korea Network Information Center, the national registry, rather than the operator directly; this is standard for Korean IP allocations. - The address inventory is finely subdivided into 103 prefixes, including multiple /20, /21, and /22 blocks, consistent with a large-scale consumer ISP managing distinct service areas or legacy allocations.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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.
