hosting ddos cloud

The AS handle AZT is held by Azure Technology Co., Limited.

What it's used for

  • The address space carries cloud and DDoS protection services, evidenced by netnames CLOUD04, CLOUD-IP, KFCTL, CTCL-HK, and M9TCL-HK associated with registrants including Kung Fu Cloud Technology Limited, ClearDDoS Technology Co Limited, and 92Cloud Technology Co., Limited.
  • The AS announces 25,344 IPv4 addresses across 27 prefixes and 15 IPv6 prefixes, while maintaining 51 observed neighbours; this ratio of address volume to peering peers indicates a hosting or content delivery role rather than a transit provider.
  • Traffic from this AS consists of web and API endpoints, DDoS mitigation infrastructure, and cloud service backends operated by the affiliated technology companies.

Notable

  • Registrants for the largest prefixes include Azure Technology Co., Limited, Kung Fu Cloud Technology Limited, ClearDDoS Technology Co Limited, and 92Cloud Technology Co., Limited, indicating a portfolio of related or acquired entities under the AS.
  • The inventory is finely subdivided into numerous /22 and /23 blocks, reflecting a segmented corporate estate for different service lines or customer 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 1,773 prefixes, as published 2026-10-13. 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.
