As of 11th November 2026, AS20845 (2Connect Telecommunications…), an access network registered in Hungary with RIPE NCC, originates 115 IPv4 prefixes covering 652k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 617th-largest of the 80,743 networks we see originating IPv4, and the 3rd-largest of 238 in Hungary. It is seen behind 6 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS9002 (RETN Limited), 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 AS20845 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.
