AS16591 — Google Fiber Inc.

Google Fiber Inc. (AS16591) operates content-delivery and edge infrastructure — the servers that sit in front of websites and deliver their pages, not the machines people browse from. 79% of the 43 addresses we have observed on it carry the datacenter flag, and that is a statement about routing, not a warning: this is what a CDN's address space is supposed to look like.

The number that matters here is different: none of the 43 observed addresses carried a notable risk score when last checked. Predax deliberately exempts recognised infrastructure operators from the datacenter risk weight — scoring a CDN's addresses as threats would push site owners into blocking the network that serves their own content.

Addresses on this network have been looked up through Predax between February 10, 2026 and August 29, 2026. Each figure on this page reflects an address's most recent check, not a permanent record.

Every observed address on this network geolocates to United States — the footprint of a network serving one region rather than globally distributed infrastructure.

Do not block this network. Its addresses are the delivery path for ordinary websites — including, very possibly, your own. A request from here is usually a CDN edge fetching or serving content, not a visitor to screen.

If an address from this network is misbehaving in your logs, judge the behaviour — the request pattern, the endpoints it touches — rather than the network. Its individual report page will show whether anything beyond the infrastructure flags was detected.
