Thank you for your feedback
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"):
206.190.208.0/21104.153.232.0/21149.137.128.0/2045.11.36.0/222605:72c0::/32
If you require IPv4 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.
IPv6 Support
The S3-Compatible API now supports IPv6.
No changes to your code should be required to use IPv6 addresses with Backblaze B2 Cloud Storage and the S3-Compatible API.

What is IPv6?
IPv6 is a version of the Internet Protocol that uses a larger address space than IPv4, its predecessor and currently the most common format for IP addresses. IPv6 addresses consist of eight groups of four hexadecimal digits with each group separated by a colon. For example:2001:db8:1f70:999:de8:7648:3a49:6e8In comparison, IPv4 notation consists of four groups of decimal digits with the groups separated by dots. For example:198.51.100.1Can I still use IPv4 addresses?
Yes. The S3-Compatible API will continue to support IPv4 addresses for the foreseeable future.Will using IPv6 incur additional costs?
No.Is IPv6 more secure than IPv4?
Requests to our APIs using IPv4 or IPv6 have equally secure connections and use the same strong TLS encryption.However, some customers may see a performance improvement if IPv6 allows them to avoid NAT.
