AS206596Computer Research Center of Islamic Sciences
As of 26th September 2026, AS206596 (Computer Research Center of Islamic…), a network registered in Iran with RIPE NCC, originates 10 IPv4 prefixes covering 3.3k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 19,533rd-largest of the 79,516 networks we see originating IPv4, and the 114th-largest of 572 in Iran. It is seen behind 2 upstream networks, most often AS51074 (GOSTARESH-E-ERTEBATAT-E MABNA COMPANY…) and AS48159 (Telecommunication Infrastructure Company), and in front of 1 downstream network. 92% of its announcements have 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 AS206596 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS206596 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.
