United StatesRegistryRIPE NCC

As of 29th September 2026, AS21313 (Verisign Anycast FR 0A), a network registered in the United States with RIPE NCC, originates 15 IPv4 prefixes covering 3.8k addresses and 14 IPv6 prefixes. By IPv4 address space that makes it the 18,617th-largest of the 79,607 networks we see originating IPv4, and the 5,122nd-largest of 18,442 in the United States. It is seen behind 1 upstream network, most often AS7342 (VeriSign Infrastructure & Operations). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 29 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS21313 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.
