As of 27th September 2026, AS43940 (MTEL d.o.o.), an access network registered in Montenegro with RIPE NCC, originates 63 IPv4 prefixes covering 50.2k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 4,444th-largest of the 79,525 networks we see originating IPv4, and the 2nd-largest of 19 in Montenegro. It is seen behind 1 upstream network, most often AS8400 (Telekom Srbija a.d.), and in front of 11 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 AS43940 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.
