Summary
CDNetworks
cdn hosting business
CDNETWORKS-AS-KR is operated by CDNetworks.
What it's used for
- The address space carries CDN infrastructure, evidenced by the consistent
CDNETWORKS-KRnetname across all sampled prefixes. - The AS announces 27,136 IPv4 addresses across 46 prefixes with only 1 observed neighbour, indicating a dedicated service network rather than a transit or access provider.
- Traffic from this AS consists of content delivery network endpoints serving web and API requests, consistent with CDNetworks' business as a CDN provider.
Notable
- Registrants align with the announcer, with all sampled prefixes registered to
IRT-KRNIC-KRunder theCDNETWORKS-KRnetname. - CDNetworks was acquired by KDDI in 2011 and subsequently by Wangsu Science & Technology in 2017.
- The inventory consists of 46 IPv4 prefixes with no IPv6 announcements, reflecting a legacy IPv4-only estate.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
