About this network

A Google Autonomous System originally allocated to YouTube. It now sits inside Google's network and carries mostly first-party media traffic, especially video delivery and edge caching.

What it's used for

• Serving YouTube and other Google media, frequently from Google Global Cache (GGC) nodes placed inside ISP networks to keep popular video close to viewers.
• Announcing content prefixes under the registry name YOUTUBE, separate from Google's primary consumer ASN AS15169 and from Google Cloud's AS396982.

Notable

• The ASN was registered in 2005, the year YouTube was founded, and predates Google's 2006 acquisition of the company. It has kept the YOUTUBE registry name even though the org record now reads Google LLC.
• PeeringDB classifies it as a Content network with global reach and a selective peering policy, consistent with a dedicated media-delivery role rather than general-purpose hosting.

Interesting

• Google splits its footprint across several ASNs by role (AS15169 for core consumer products, AS396982 for Google Cloud, and this one rooted in YouTube's origins), so which ASN an IP lands in hints at which part of Google you are actually talking to.
