AustriaRegistryRIPE NCCTypeCarrier

As of 11th November 2026, AS1764 (Next Layer Telecommunications), a transit carrier registered in Austria with RIPE NCC, originates 70 IPv4 prefixes covering 97.3k addresses and 13 IPv6 prefixes. By IPv4 address space that makes it the 2,487th-largest of the 80,743 networks we see originating IPv4, and the 13th-largest of 624 in Austria. It is seen behind 42 upstream networks, most often AS2914 (NTT America, Inc.) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 134 downstream networks. 60% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 99% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS1764 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.
