As of 26th September 2026, AS30456 (Cosmic Global Networks), a transit carrier registered in the United States with ARIN, originates 23 IPv4 prefixes covering 5.9k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 14,498th-largest of the 79,480 networks we see originating IPv4, and the 4,136th-largest of 18,421 in the United States. It is seen behind 5 upstream networks, most often AS2914 (NTT America, Inc.) and AS13335 (Cloudflare, Inc.), and in front of 17 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 AS30456 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.
