United KingdomRegistryRIPE NCC

As of 10th November 2026, AS210457 (Kyonix Networks Limited), a network registered in the United Kingdom with RIPE NCC, originates 12 IPv4 prefixes covering 3.1k addresses and 19 IPv6 prefixes. By IPv4 address space that makes it the 20,470th-largest of the 80,733 networks we see originating IPv4, and the 637th-largest of 2,122 in the United Kingdom. It is seen behind 1 upstream network, most often AS58212 (dataforest GmbH), and in front of 1 downstream network. 42% of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. 94% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS210457 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.
