United StatesRegistryARIN

As of 23rd October 2026, AS3630 (NYSERNet), a network registered in the United States with ARIN, originates 2 IPv4 prefixes covering 512 addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 48,614th-largest of the 79,652 networks we see originating IPv4, and the 10,384th-largest of 18,475 in the United States. It is seen behind 2 upstream networks, most often AS49544 (i3D.net B.V) and AS3755 (NYSERNet), and in front of 61 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 75% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS3630 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.
