About this network

MACKAY-AS-AP is Mackay Telecommunication Inc. (瑪凱電信), a Taiwanese telecommunications operator based in the Taipei area. Despite the name, it has nothing to do with Mackay in Queensland: the network is Taiwanese, its address space is TWNIC-managed, and its reverse DNS resolves under mky.com.

What it's used for

• Telecom services in Taiwan. The company grew out of the store-and-forward messaging era and now centres on VoIP and IP communications alongside data connectivity.
• It announces 211.76.0.0/19 and the 210.244.192.0/19 range, with generic per-address reverse DNS of the form …MKY-IP.mky.com across the space. That flat naming gives no subscriber-pool signal either way.

Notable

• The name is a trap worth flagging: an Australian city, an American marine-communications firm (Mackay Communications), and this Taiwanese carrier all share it. The registry contacts and the TWNIC address space are what settle the question.
• Two /19s is a small footprint for a licensed carrier, consistent with a niche operator in voice and messaging rather than a mass-market access ISP.
