Facebook, like other large online services, does not rely on a single IP address. Instead, it utilizes a vast number of IP addresses distributed across numerous ranges (also known as Netblocks) to handle its massive infrastructure, including servers, data centers, and content delivery networks.
These IP ranges are allocated and managed by the company, Facebook, Inc., often under specific Autonomous System Numbers (ASNs). According to the provided references regarding AS32934, Facebook, Inc. controls several significant IP blocks.
Key Facebook IP Ranges (AS32934)
The following table lists some of the IP ranges associated with Facebook, Inc., as detailed in the reference information:
