AS65521

As of 13th November 2026, AS65521 originates 12 IPv4 prefixes covering 3.1k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 20,503rd-largest of the 80,827 networks we see originating IPv4. It is seen behind 2 upstream networks, most often AS8551 (Bezeq International Ltd.) and AS23956 (AmberIT Limited), and in front of 1 downstream network. None of its announcements have a valid RPKI ROA; 14 are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 14 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS65521 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.
