As of 24th October 2026, AS97 (NTT America, Inc.), a network registered in the United States with ARIN, originates 2 IPv4 prefixes covering 512 addresses. By IPv4 address space that makes it the 48,613th-largest of the 79,671 networks we see originating IPv4, and the 10,391st-largest of 18,487 in the United States. It is seen behind 3 upstream networks, most often AS3356 (Lumen (Level 3)) and AS3257 (GTT Communications Inc.). 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 AS97 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.
