As of 22nd October 2026, AS1218 (Oracle Corporation), a network registered in the United States with ARIN, originates 23 IPv4 prefixes covering 17.7k addresses and 19 IPv6 prefixes. By IPv4 address space that makes it the 7,579th-largest of the 79,655 networks we see originating IPv4, and the 2,437th-largest of 18,475 in the United States. It is seen behind 3 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS3356 (Lumen (Level 3)). 2% of its announcements have 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 AS1218 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.
