As of 11th November 2026, AS21299 (Kar-Tel LLC), an access network registered in Kazakhstan with RIPE NCC, originates 757 IPv4 prefixes covering 545k addresses and 11 IPv6 prefixes. By IPv4 address space that makes it the 690th-largest of the 80,743 networks we see originating IPv4, and the 3rd-largest of 218 in Kazakhstan. It is seen behind 3 upstream networks, most often AS35168 (TNS-Plus LLP) and AS15549 (National Information Technologies…), and in front of 27 downstream networks. Under 1% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS21299 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.
