As of 11th November 2026, AS38450 (Ministry of Infomation Communication…), a network registered in Thailand with APNIC, originates 30 IPv4 prefixes covering 50.2k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 4,505th-largest of the 80,743 networks we see originating IPv4, and the 39th-largest of 464 in Thailand. It is seen behind 3 upstream networks, most often AS4651 (The Communications Authority of…) and AS38040 (TOT Public Company Limited), and in front of 2 downstream networks. None of its announcements have a valid RPKI ROA. 35% of its routes reach at least 90% of full-feed peers, and 22 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS38450 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.
