LatviaRegistryRIPE NCC

As of 10th November 2026, AS29345 (Institute of Mathematics and Computer…), a network registered in Latvia with RIPE NCC, originates 5 IPv4 prefixes covering 1.8k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 30,392nd-largest of the 80,733 networks we see originating IPv4, and the 53rd-largest of 249 in Latvia. It is seen behind 2 upstream networks, most often AS8194 (Latvia State Radio and Television Centre) and AS5538 (Institute of Mathematics and Computer…). 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 AS29345 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.
