Action Needed For Customers Who Self-Host Blackbaud Net Community

Mike Rusche

For customers who self-host Blackbaud Net Community, on October 5th, 2021, Blackbaud will make a change to enhance the security of the Blackbaud Payment Service™ that requires your attention. Again, this is only for customers who self-host their Blackbaud Net Community.

On October 5th, 2021, Blackbaud will make a change to enhance the security of the Blackbaud Payment Service™ that requires your attention. This change will impact the IP addresses associated with Blackbaud Payment Service™, and updates are required for self-hosted customers to avoid disrupting your payment processing.

If your organization self-hosts Blackbaud applications – such as Blackbaud NetCommunity™, Blackbaud Internet Solutions™, Blackbaud CRM™, or Raiser's Edge™ – and uses Internet Protocol (IP) address-based firewall rules, you must allow all traffic from the IP addresses used by Section.IO below. They are a third-party service utilized by Blackbaud for networking purposes. The following CIDRs (IP ranges) must be allowed:

207.120.32.0/20 (207.120.32.0 - 207.120.47.255)

209.160.100.0/22 (209.160.100.0 - 209.160.103.255)


Allowing these new IP addresses will avoid a disruption in your payment processing service.

If your Blackbaud applications are all hosted by Blackbaud, no action is required. Additionally, self-hosted customers who use hostname-based firewall rules do not need to take action. For more information, please review Knowledgebase article KB 50865.

If you have any questions, please contact Customer Support.
