United StatesRegistryARIN

As of 27th September 2026, AS2711 (Spirit Communications), a network registered in the United States with ARIN, originates 134 IPv4 prefixes covering 408k addresses and 6 IPv6 prefixes. By IPv4 address space that makes it the 803rd-largest of the 79,523 networks we see originating IPv4, and the 200th-largest of 18,427 in the United States. It is seen behind 8 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS2914 (NTT America, Inc.), and in front of 82 downstream networks. None of its announcements have a valid RPKI ROA. Over 99% 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 AS2711 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.
