AS7The Defence Science and Technology Laboratory

European UnionRegistryRIPE NCC

As of 11th November 2026, AS7 (The Defence Science and Technology…), a network registered in European Union with RIPE NCC, originates 18 IPv4 prefixes covering 94.5k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 2,530th-largest of the 80,743 networks we see originating IPv4, and the 20th-largest of 201 in European Union. It is seen behind 3 upstream networks, most often AS786 (Jisc Services Limited) and AS327708 (Airtel Rwanda Ltd), and in front of 1 downstream network. 37% 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.

Networks observed one and two hops upstream of AS7 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.
