About this network

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.
