BelgiumRegistryRIPE NCC

As of 26th September 2026, AS31713 (Gateway Communications), a network registered in Belgium with RIPE NCC, originates 256 IPv4 prefixes covering 695k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 576th-largest of the 79,516 networks we see originating IPv4, and the 6th-largest of 271 in Belgium. It is seen behind 1 upstream network, most often AS3741 (Dimension Data), and in front of 25 downstream networks. 99% of its announcements have a valid RPKI ROA; 3 are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 258 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS31713 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.
