AS8068Microsoft Corporation
United StatesRegistryARINAs of 27th September 2026, AS8068 (Microsoft Corporation), a network registered in the United States with ARIN, originates 39 IPv4 prefixes covering 10k addresses and 31 IPv6 prefixes. By IPv4 address space that makes it the 10,564th-largest of the 79,540 networks we see originating IPv4, and the 3,202nd-largest of 18,430 in the United States. It is seen behind 1 upstream network, most often AS8075 (Microsoft Corporation). 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 AS8068 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS8068 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.
