cable residential korea access

The AS handle GCNCATV-AS-KR is held by Gyounggidongbu Cable TV Co., Ltd.

What it's used for

  • The address space carries residential cable television and internet access services, indicated by the netname DLIVE-KR across all announced prefixes.
  • The AS announces 23,552 IPv4 addresses across 9 prefixes, with a single observed neighbour, a ratio that implies a local access or eyeball network rather than a transit provider.

Notable

  • All registrants are listed as IRT-KRNIC-KR, which is the generic Korea Network Information Center handle, rather than a specific corporate registrant name.
  • The address inventory consists of multiple /20 and /21 blocks, primarily within the 121.100.0.0/16 range, along with smaller /22 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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
