Can an IP address and a domain name be included in the same certificate?

This mainly depends on whether you need a public trusted certificate or a private self-signed certificate

Public CA certificates: They cannot contain both public IP addresses and private IP addresses. Since IP addresses require validation, only validated IP addresses can be included. Self-signed/Private CA certificates: Technically, they can include both public and private IP addresses. When you purchase a self-signed certificate/private network certificate, no IP validation is required, and the certificate can be issued directly. Please note that you need to import the root certificate to each client when installing and using the certificate.

Explanation:

1. Self-signed/private CA certificates include CFCA standard server certificates and sslTrus self-signed certificates. You can save your order as a draft and contact our customer service to explain your requirements.
2. Choose the certificate type based on your actual needs: if your IP address cannot pass validation but you have encryption requirements, you can use a self-signed certificate; if your IP address can be validated, a public CA certificate is preferred.
