About this network

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.
