AS8657MEO International Backbone
As of 27th September 2026, AS8657 (MEO International Backbone), a transit carrier registered in Portugal with RIPE NCC, originates 3 IPv4 prefixes covering 11.3k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 9,862nd-largest of the 79,525 networks we see originating IPv4, and the 18th-largest of 126 in Portugal. It is seen behind 41 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS6939 (Hurricane Electric LLC), 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.

Upstream graph
The networks AS8657 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS8657 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.
