United StatesRegistryRIPE NCC

As of 27th September 2026, AS210329 (Kamatera Inc), a network registered in the United States with RIPE NCC, originates 37 IPv4 prefixes covering 9.5k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 10,838th-largest of the 79,525 networks we see originating IPv4, and the 3,261st-largest of 18,428 in the United States. It is seen behind 2 upstream networks, most often AS174 (Cogent Communications, LLC) and AS3257 (GTT Communications Inc.), and in front of 1 downstream network. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 97% 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 AS210329 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.
