Summary

Kwangju Broadcasting Corporation

Korea, Republic of · AI-generated

broadcasting media kr

The AS handle KCTVNET-AS-KR is held by Kwangju Broadcasting Corporation.

What it's used for

  • The address space carries infrastructure for a regional broadcasting corporation, as indicated by the netname KCTVNET-KR and the registrant IRT-KRNIC-KR.
  • The network announces 34,816 IPv4 addresses across 7 prefixes with only 2 observed neighbours, a ratio that indicates an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal network operations and media distribution endpoints for the Gwangju-based radio and television station.

Notable

  • All seven announced prefixes share the netname KCTVNET-KR and the registrant IRT-KRNIC-KR, which aligns with the AS holder Kwangju Broadcasting Corporation.
  • The address inventory consists of a mix of /19, /20, and /22 blocks, including 111.91.160.0/19, 119.77.96.0/19, and 123.100.160.0/19.

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: 436 networks and 1,771 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.
