ThailandRegistryAPNIC

As of 12th November 2026, AS9587 (DTAC (True)), a network registered in Thailand with APNIC, originates 75 IPv4 prefixes covering 264k addresses and 52 IPv6 prefixes. By IPv4 address space that makes it the 1,103rd-largest of the 80,772 networks we see originating IPv4, and the 17th-largest of 464 in Thailand. It is seen behind 3 upstream networks, most often AS38082 (True International Gateway Co., Ltd.) and AS133543 (Real Future Company Limited), and in front of 9 downstream networks. 9% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 91% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS9587 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
