AS213840DDOS PROTECTION LTD
United KingdomRegistryRIPE NCCAs of 23rd October 2026, AS213840 (DDOS PROTECTION LTD), a network registered in the United Kingdom with RIPE NCC, originates 19 IPv4 prefixes covering 4.9k addresses. By IPv4 address space that makes it the 15,834th-largest of the 79,659 networks we see originating IPv4, and the 480th-largest of 2,077 in the United Kingdom. It is seen behind 2 upstream networks, most often AS1002 (Bytefilter LLC) and AS40065 (CNSERVERS LLC). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 79% of its routes reach at least 90% of full-feed peers, and 4 prefixes are also originated by another network.

Upstream graph
The networks AS213840 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS213840 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.
