Summary

NHN Cloud

Korea, Republic of · AI-generated

cloud hosting korea enterprise

NHN-AS-KR is operated by NHN Cloud.

What it's used for

  • The address space carries cloud and enterprise infrastructure, evidenced by netnames NHNCLOUD-NET-KR and NHN.
  • The AS announces 97,536 IPv4 addresses across 105 prefixes with 8 observed neighbours, indicating a large-scale hosting or cloud provider rather than a transit or access network.
  • Traffic from this AS consists of web services, API endpoints, and cloud workloads for NHN Cloud's customers.

Notable

  • Registrants include Japan Network Information Center for prefixes with netname NHN, and IRT-KRNIC-KR for NHNCLOUD-NET-KR and BORANET-KR prefixes.
  • The inventory includes a mix of netnames, including APNIC-AP for some prefixes, reflecting historical allocation or leasing arrangements.
  • The address inventory is finely subdivided into 105 prefixes, consistent with an internal corporate estate or cloud provider managing distinct service segments.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,771 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

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.
