As of 27th September 2026, AS28022 (CRISP S.A.), a network registered in Costa Rica with LACNIC, originates 16 IPv4 prefixes covering 4.1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 17,073rd-largest of the 79,540 networks we see originating IPv4, and the 20th-largest of 83 in Costa Rica. It is seen behind 1 upstream network, most often AS52468 (UFINET PANAMA S.A.), and in front of 3 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 AS28022 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.
