As of 22nd October 2026, AS553 (BelWü), an access network registered in Germany with RIPE NCC, originates 96 IPv4 prefixes covering 2.3M addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 238th-largest of the 79,655 networks we see originating IPv4, and the 8th-largest of 2,306 in Germany. It is seen behind 38 upstream networks, most often AS2914 (NTT America, Inc.) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 16 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 AS553 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.
