United StatesRegistryARIN

As of 10th November 2026, AS22516 (Charter Communications LLC), a network registered in the United States with ARIN, originates 120 IPv4 prefixes covering 1.1M addresses and 11 IPv6 prefixes. By IPv4 address space that makes it the 443rd-largest of the 80,733 networks we see originating IPv4, and the 101st-largest of 18,751 in the United States. It is seen behind 2 upstream networks, most often AS7843 (Spectrum (Charter)) and AS20115 (Spectrum (Charter)), and in front of 16 downstream networks. Every one of its announcements has 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 AS22516 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.
