SwedenRegistryRIPE NCCTypeCarrier

As of 28th September 2026, AS3399 (Obenet AB), a transit carrier registered in Sweden with RIPE NCC, originates 27 IPv4 prefixes covering 33.5k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 5,348th-largest of the 79,544 networks we see originating IPv4, and the 53rd-largest of 643 in Sweden. It is seen behind 34 upstream networks, most often AS6453 (TATA Communications (America) Inc) and AS3257 (GTT Communications Inc.), and in front of 49 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.

Upstream graph

The networks AS3399 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS3399 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.
