AS1120ACONET

European UnionRegistryRIPE NCC

As of 22nd October 2026, AS1120 (ACONET), a network registered in European Union with RIPE NCC, originates 3 IPv4 prefixes covering 528 addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 48,610th-largest of the 79,663 networks we see originating IPv4, and the 89th-largest of 179 in European Union. It is seen behind 13 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS9002 (RETN Limited), and in front of 3 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS1120 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.
