As of 11th November 2026, AS210000 (TwentyWAN MB), a transit carrier registered in Lithuania with RIPE NCC, originates 8 IPv4 prefixes covering 2k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 25,846th-largest of the 80,733 networks we see originating IPv4, and the 85th-largest of 175 in Lithuania. It is seen behind 6 upstream networks, most often AS6424 (EDGOO NETWORKS) and AS6939 (Hurricane Electric LLC), and in front of 4 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 AS210000 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.
