TürkiyeRegistryRIPE NCC

As of 24th October 2026, AS6823 (3C1B Telekomunikasyon ve Internet Hiz.…), a network registered in Türkiye with RIPE NCC, originates 20 IPv4 prefixes covering 8.7k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 11,421st-largest of the 79,671 networks we see originating IPv4, and the 65th-largest of 864 in Türkiye. It is seen behind 38 upstream networks, most often AS2914 (NTT America, Inc.) and AS5405 (Inter.link GmbH), and in front of 6 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 90% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS6823 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS6823 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.
