Summary
Total Access Communication (dtac) — DTN
DTNCORP-TH-AP is registered to Total Access Communication PLC, the Thai mobile operator that traded as dtac. DTN is dtac TriNet, the licensed subsidiary that held dtac's 3G/4G spectrum and ran the network under it.
What it's used for
dtac was founded in 1989 and grew into Thailand's number-three mobile network, majority-influenced by Telenor. In 2023 it amalgamated with True Corporation in a $7.3 billion deal that produced the country's largest operator; the merged entity kept the True brand, though regulators required the two customer bases to be served separately for a transition period. This AS is part of the mobile plumbing that survived that reorganisation.
Notable
The kind is mobile, established by the holder rather than by size — and the size is worth being precise about, because it is small. RIS sees only 4 IPv4 prefixes / 1,024 addresses (four /24s inside 115.67.0.0) plus one 2404:8d04::/32 IPv6 allocation, with 6 observed neighbours. That is emphatically not dtac's subscriber pool; a network carrying twenty million handsets needs orders of magnitude more space, and it announces it from other ASNs. What a footprint like this typically carries is operator infrastructure — interconnect, roaming, signalling, services — rather than the eyeball pool itself. The IPv6 /32 is the giveaway that this is a licensed carrier's allocation and not an enterprise's.
Interesting
Treat any geolocation of these four /24s with care. They are carrier infrastructure inside a company that has since been absorbed, and the registration lags the corporate reality by several years.

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.
