TürkiyeRegistryRIPE NCC

As of 27th September 2026, AS210538 (KEYUBU Internet ve Bilisim Tic. Ltd.…), a network registered in Türkiye with RIPE NCC, originates 27 IPv4 prefixes covering 6.9k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 13,309th-largest of the 79,525 networks we see originating IPv4, and the 78th-largest of 858 in Türkiye. It is seen behind 2 upstream networks, most often AS219384 (Satcore LLC) and AS60446 (Datema Bilisim Ticaret Anonim Sirketi), and in front of 2 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 AS210538 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.
