About this network

The AS handle F5 is held by F5 Networks SARL, the French subsidiary of F5 Inc.

What it's used for

• The address space carries corporate infrastructure and cloud services, evidenced by netnames such as F5-DISTRIBUTED-CLOUD-1, F5-inc, and FR-F5-20190409.
• With 55,808 IPv4 addresses announced across 42 prefixes and 6,459 observed neighbours, the high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a residential access network.

Notable

• Registrants are consistent with the announcer, primarily listing F5 Inc. - Network Engineering and F5 Networks SARL, with one prefix registered to Brink's, Incorporated.
• F5 Inc. acquired Volterra, Inc., which is reflected in the VOLTERRA-AP netname and reverse DNS entries pointing to volterra.us.
• The inventory includes a mix of large blocks in the 159.60.0.0/16 range and smaller /22 and /23 allocations across various global regions.
