security business corporate korea

AHNLAB-AS-KR is operated by AhnLab, Inc.

What it's used for

  • The address space carries corporate infrastructure for a cybersecurity firm, evidenced by the netname AHNLAB-KR and registrant IRT-KRNIC-KR.
  • The AS announces 8192 IPv4 addresses within a single prefix (210.112.192.0/19) and maintains 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, with AHNLAB-KR and IRT-KRNIC-KR confirming ownership by AhnLab.
  • AhnLab is a South Korean cybersecurity company founded in 1995, known for its V3 anti-malware products and AI-powered security platform.
  • The inventory consists of one contiguous /19 block, typical of a single corporate site or internal network segmentation.

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 2026-10-24. 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.
