As of 26th September 2026, AS6736 (Institute for Research in Fundamental…), an access network registered in Iran with RIPE NCC, originates 15 IPv4 prefixes covering 232k addresses. By IPv4 address space that makes it the 1,184th-largest of the 79,516 networks we see originating IPv4, and the 11th-largest of 572 in Iran. It is seen behind 1 upstream network, most often AS39533 (Asympto Networks Kft.), and in front of 25 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 AS6736 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.
