AS38444Super Broadband Network

ThailandRegistryAPNIC

As of 27th September 2026, AS38444 (Super Broadband Network), a network registered in Thailand with APNIC, originates 65 IPv4 prefixes covering 51.2k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 4,390th-largest of the 79,525 networks we see originating IPv4, and the 38th-largest of 456 in Thailand. It is seen behind 1 upstream network, most often AS45430 (SBN-IIG/AWN-IIG transit provider). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS38444 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.
