        Article Summary

        All of the traffic for Backblaze services use the same IP ranges. The Backblaze data center servers are located at IP addresses in the following ranges (in "CIDR notation"):

        • 206.190.208.0/21
        • 104.153.232.0/21
        • 149.137.128.0/20
        • 45.11.36.0/22 
        • 2605:72c0::/32

        If you require Pv4 notation, you can convert the above IP addresses using a tool such as this one.

        All Backblaze servers use the *.backblaze.com or *backblazeb2.com domains, so it may be easiest to whitelist the appropriate domains.

        Note
        Backblaze periodically adds more computers so this information may change in the future.

        Backblaze uses Cloudflare for www.backblaze.com, help.backblaze.com, and www.backblaze.com/docs, so you will see out of block addresses in use for those web pages.
