NetherlandsRegistryAPNIC

As of 24th October 2026, AS18381 (RedSwitches), a network registered in the Netherlands with APNIC, originates 3 IPv4 prefixes covering 768 addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 44,949th-largest of the 79,642 networks we see originating IPv4, and the 613th-largest of 1,022 in the Netherlands. It is seen behind 3 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS3257 (GTT Communications Inc.). 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 AS18381 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.
