Summary

abcle

Korea, Republic of · AI-generated

korea business ipv4

The AS handle HCLC-AS-KR is held by abcle.

What it's used for

  • The address space carries blocks registered under netnames DURUAN-KR, HINETWORKS-KR, and TRIZNNETWORKS-KR, all associated with the IRT-KRNIC-KR registrant.
  • The AS announces 362,496 IPv4 addresses across 103 prefixes, with 7 observed neighbours, indicating a role consistent with an access or internal corporate network rather than a transit provider.
  • The inventory consists entirely of IPv4 space; no IPv6 prefixes are announced.

Notable

  • Registrants for the largest prefixes are primarily IRT-KRNIC-KR, with some blocks held by APNIC Hostmaster under the netname APNIC-AP.
  • The address inventory is fragmented into 103 distinct IPv4 prefixes, including several /17 and /18 blocks, suggesting a subdivided corporate or service estate.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
