United StatesRegistryARIN

As of 11th November 2026, AS27446 (ERC Broadband), a network registered in the United States with ARIN, originates 14 IPv4 prefixes covering 42.5k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 4,829th-largest of the 80,743 networks we see originating IPv4, and the 1,694th-largest of 18,754 in the United States. It is seen behind 3 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS2914 (NTT America, Inc.), and in front of 19 downstream networks. 82% of its announcements have a valid RPKI ROA; 2 are RPKI-invalid. 47% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS27446 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.
