ENGTAC-AS-TH-AP is the autonomous system for dtac (Total Access Communication PLC).

What it's used for

  • The address space carries mobile subscriber traffic, evidenced by netnames DTAC-MOBILE-AP01 and DTAC-MOBILE-AP02 across the largest prefixes.
  • The AS announces 101,376 IPv4 addresses and 34 IPv6 prefixes, with 61 prefixes located in Thailand.
  • With only 1 observed neighbour, the high address count relative to peer count indicates an access/eyeball network rather than a transit provider.

Notable

  • Registrants for the major prefixes are consistently DTAC NETWORK - Network Administrator and DTAC NETWORK - Network Operation Center - NOC, aligning with the AS holder.
  • The address inventory is dominated by large /19 blocks in the 1.46.0.0 and 1.47.0.0 ranges, supplemented by smaller /21, /22, /23, and /24 blocks in the 111.84.0.0 and 59.153.0.0 ranges.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,775 prefixes, as published 2026-10-11. 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.
