United StatesRegistryARIN

As of 11th November 2026, AS62 (CyrusOne LLC), a network registered in the United States with ARIN, originates 161 IPv4 prefixes covering 170k addresses and 10 IPv6 prefixes. By IPv4 address space that makes it the 1,544th-largest of the 80,747 networks we see originating IPv4, and the 445th-largest of 18,752 in the United States. It is seen behind 5 upstream networks, most often AS6461 (Zayo Bandwidth) and AS3356 (Lumen (Level 3)), and in front of 75 downstream networks. None of its announcements have a valid RPKI ROA. 99% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS62 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.
