IranRegistryRIPE NCC

As of 26th September 2026, AS41881 (Fanava Group), a network registered in Iran with RIPE NCC, originates 60 IPv4 prefixes covering 18.9k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 7,295th-largest of the 79,516 networks we see originating IPv4, and the 39th-largest of 572 in Iran. It is seen behind 3 upstream networks, most often AS43754 (Asiatech Data Transmission company) and AS42337 (Respina Networks & Beyond PJSC), and in front of 18 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 AS41881 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.
