As of 26th September 2026, AS17660 (DrukNet ISP), a network registered in Bhutan with APNIC, originates 13 IPv4 prefixes covering 23k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 6,517th-largest of the 79,480 networks we see originating IPv4, and the largest of 27 in Bhutan. It is seen behind 22 upstream networks, most often AS2914 (NTT America, Inc.) and AS6453 (TATA Communications (America) Inc), and in front of 712 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 87% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS17660 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.
