United StatesRegistryARIN

As of 24th October 2026, AS2722 (CULR, LLC), a network registered in the United States with ARIN, originates 5 IPv4 prefixes covering 9.2k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 10,994th-largest of the 79,664 networks we see originating IPv4, and the 3,311th-largest of 18,488 in the United States. It is seen behind 4 upstream networks, most often AS2721 (CULR, LLC) and AS10490 (Georgia Institute of Technology), and in front of 5 downstream networks. None of its announcements have a valid RPKI ROA. 86% 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 AS2722 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.
