Summary

Daou Technology

Korea, Republic of · AI-generated

business korea it corporate

DAOU-AS-KR is held by Daou Technology.

What it's used for

  • The address space carries corporate infrastructure, with all sampled prefixes registered under the netname DAOU-KR and registrant IRT-KRNIC-KR.
  • The AS announces 175360 IPv4 addresses across 112 prefixes, while maintaining only 3 observed neighbours, a ratio indicative of an internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers and web/API endpoints for Daou Technology, a South Korean multinational specializing in marketing communication and IT solutions.

Notable

  • Registrants agree with the announcer, with all sampled prefixes showing DAOU-KR as the netname and IRT-KRNIC-KR as the registrant.
  • The address inventory is finely subdivided into numerous /20 and /21 blocks, consistent with site-by-site segmentation for a large corporate entity.

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 1,772 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

2 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
