As of 11th November 2026, AS200193 (ITM Yazilim Bilgisayar Sistemleri ve…), a network registered in Türkiye with RIPE NCC, originates 4 IPv4 prefixes covering 1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 36,497th-largest of the 80,747 networks we see originating IPv4, and the 276th-largest of 870 in Türkiye. It is seen behind 2 upstream networks, most often AS62403 (PletX GmbH) and AS212219 (HOSTING DUNYAM BILISIM TEKNOLOJILERI…). 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 AS200193 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.
