About this network

FORTINET is operated by Fortinet Inc., a cybersecurity company headquartered in Sunnyvale, California.

What it's used for

• The address space carries Fortinet's own infrastructure, with netnames including FTC-58, FORTINET, FORTISASE, and FORTIGUARD registered to Fortinet Inc. or Fortinet Technologies.
• The AS announces 86,528 IPv4 addresses across 143 prefixes and 6 IPv6 prefixes, while maintaining 197 observed neighbours; this high neighbour count relative to the address block size indicates a transit or peering-heavy role for a global enterprise network.
• Traffic from this AS consists of web/API endpoints, management interfaces, and security appliance traffic for Fortinet's global operations and customer-facing services.

Notable

• Registrants largely align with the announcer, with most prefixes registered to Fortinet Inc., though two prefixes (154.52.0.0/20 and 38.21.200.0/22) are registered to Cogent Communications, LLC.
• The address inventory is finely subdivided into numerous /21 and /22 blocks, consistent with an internal corporate estate segmented by site or function rather than a single contiguous allocation.
