As of 22nd October 2026, AS288 (European Space Agency (ESA)), an access network registered in Germany with RIPE NCC, originates 54 IPv4 prefixes covering 19.2k addresses. By IPv4 address space that makes it the 7,262nd-largest of the 79,655 networks we see originating IPv4, and the 263rd-largest of 2,306 in Germany. It is seen behind 3 upstream networks, most often AS3257 (GTT Communications Inc.) and AS766 (Entidad Publica Empresarial Red.es). 2% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 98% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS288 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.
