UltraDNS supports DNS-based certificate validation using Let’s Encrypt automation tools. Customers who use Let’s Encrypt for certificate issuance can automate DNS challenge verification with tools that integrate directly with UltraDNS.
Let’s Encrypt Automation with LEGO
One commonly used automation tool for Let’s Encrypt is LEGO (Let’s Encrypt Go).
LEGO provides automated certificate issuance and renewal and supports DNS-based challenge verification through integrated DNS providers.
UltraDNS Support in LEGO
UltraDNS is supported as a DNS provider in LEGO, allowing DNS challenge verification to be performed through the UltraDNS API.
Support for UltraDNS is available starting with LEGO version 4.10.0.
Important Notes
- DNS challenge verification requires API access to UltraDNS.
- Credentials and permissions must allow record creation and deletion.
- Certificate automation behavior is controlled by the LEGO tool, not UltraDNS.
