United KingdomRegistryRIPE NCCTypeCarrier

As of 12th November 2026, AS8943 (Jump Networks Ltd), a transit carrier registered in the United Kingdom with RIPE NCC, originates 7 IPv4 prefixes covering 12.5k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 9,460th-largest of the 80,772 networks we see originating IPv4, and the 287th-largest of 2,122 in the United Kingdom. It is seen behind 2 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS5405 (Inter.link GmbH), and in front of 9 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 AS8943 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.
