United StatesRegistryARINTypeEyeball

As of 27th September 2026, AS30600 (Metronet), an access network registered in the United States with ARIN, originates 207 IPv4 prefixes covering 513k addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 710th-largest of the 79,536 networks we see originating IPv4, and the 175th-largest of 18,430 in the United States. It is seen behind 4 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS2914 (NTT America, Inc.), and in front of 63 downstream networks. 16% of its announcements have 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 AS30600 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.
