Summary

Mackay Telecommunication Inc.

Taiwan · AI-generated

isp legacy

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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.
