As of 13th October 2026, AS1853 (ACONET), an access network registered in Austria with RIPE NCC, originates 17 IPv4 prefixes covering 335k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 899th-largest of the 79,585 networks we see originating IPv4, and the 5th-largest of 615 in Austria. It is seen behind 18 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS1764 (Next Layer Telecommunications), and in front of 50 downstream networks. 32% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 89% 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.
