As of 11th November 2026, AS1853 (ACONET), an access network registered in Austria with RIPE NCC, originates 18 IPv4 prefixes covering 400k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 823rd-largest of the 80,743 networks we see originating IPv4, and the 5th-largest of 624 in Austria. It is seen behind 17 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS1764 (Next Layer Telecommunications), and in front of 50 downstream networks. 30% of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. 85% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS1853 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.
