IsraelRegistryRIPE NCC

As of 24th October 2026, AS378 (IUCC - Israel InterUniversity…), a network registered in Israel with RIPE NCC, originates 61 IPv4 prefixes covering 2M addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 274th-largest of the 79,682 networks we see originating IPv4, and the 2nd-largest of 320 in Israel. It is seen behind 3 upstream networks, most often AS21320 (GEANT Vereniging) and AS35280 (F5 Networks SARL), and in front of 1 downstream network. 97% 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.

Networks observed one and two hops upstream of AS378 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.
