Autonomous system
AS21030 CDNNOW-AS
Hosting RIPE Content
Summary
Docker
cdn hosting business russia
The AS handle CDNNOW-AS is operated by Docker, a Russian content delivery network and hosting provider.
What it's used for
- The address space carries CDN and hosting infrastructure, evidenced by netnames
RU-DOCKER-CDNandRU-DOCKER-CDN-2, and reverse DNS entries pointing todocker.ru. - With 3328 IPv4 addresses announced across 8 prefixes and 53 observed neighbours, the ratio suggests a content delivery or hosting role rather than a large-scale transit provider.
Notable
- Most registrants are listed as "CEO; Cluster LLC; Abuse-C Role", aligning with the registry holder "Cluster LLC", while one prefix is registered to "Hong Xing Yao SDN. BHD.".
- The address inventory is finely subdivided into multiple /24 and /23 blocks, consistent with an internal corporate estate or segmented CDN infrastructure.

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: 431 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.
