Summary

CMC Telecom

Vietnam · AI-generated

cloud hosting datacenter

A network of CMC Telecom, one of Vietnam's larger telecom and data-center operators. Its CMC Cloud arm runs Tier III data centers in Hanoi and Ho Chi Minh City and a regional backbone across Southeast Asia.

What it's used for

  • Cloud servers, hosting, colocation, and connectivity out of CMC's Vietnamese data centers, plus the CMC Cloud IaaS/PaaS platform.

Notable

  • An IP here identifies CMC as the host, not the operator of the hosted service.
  • CMC was the first data-center operator in Vietnam to achieve PCI-DSS certification and is expanding with a large hyperscale build in Ho Chi Minh City.

Interesting

  • CMC connects to several submarine cable systems (AAE1, APG, Unity, Faster, A-Grid), which underpins its role as a Vietnamese international gateway.

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 1,783 prefixes, as published 2026-10-17. 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.
