LatviaRegistryRIPE NCC

As of 10th November 2026, AS5518 (SIA Tet), a network registered in Latvia with RIPE NCC, originates 22 IPv4 prefixes covering 101k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 2,399th-largest of the 80,733 networks we see originating IPv4, and the 4th-largest of 249 in Latvia. It is seen behind 2 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS12578 (SIA Tet), and in front of 21 downstream networks. 92% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 96% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS5518 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.
