United StatesRegistryARIN

As of 11th November 2026, AS16851 (NebraskaLink), a network registered in the United States with ARIN, originates 8 IPv4 prefixes covering 5.6k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 14,970th-largest of the 80,743 networks we see originating IPv4, and the 4,263rd-largest of 18,754 in the United States. It is seen behind 2 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 18 downstream networks. 90% 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 AS16851 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.
