United KingdomRegistryRIPE NCC

As of 27th September 2026, AS8801 (Rocket Fibre Ltd), a network registered in the United Kingdom with RIPE NCC, originates 7 IPv4 prefixes covering 9.7k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 10,680th-largest of the 79,525 networks we see originating IPv4, and the 326th-largest of 2,074 in the United Kingdom. It is seen behind 42 upstream networks, most often AS9002 (RETN Limited) and AS6453 (TATA Communications (America) Inc), and in front of 9 downstream networks. 78% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS8801 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS8801 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.
