As of 11th November 2026, AS12578 (SIA Tet), an access network registered in Latvia with RIPE NCC, originates 60 IPv4 prefixes covering 537k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 697th-largest of the 80,743 networks we see originating IPv4, and the largest of 249 in Latvia. It is seen behind 47 upstream networks, most often AS2914 (NTT America, Inc.) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 92 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 AS12578 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.
