How to verify domain name ownership by applying for SSL certificate
When applying for a domain name certificate, the system will provide the following three ways to verify the ownership of the domain name. Please select one of them to verify the domain name according to your actual situation:
1. Administrator mailbox verification
The system will send a verification email to the administrator mailbox of your choice, receive the verification email, and click the verification link in the email to complete the verification.
The domain name administrator mailbox must comply with any of the following rules:
1. Domain name whois management contact mailbox
two。 Domain name whois technical contact email
3. Mailbox with default administrator prefix:
Admin@domain.com
Administrator@domain.com
Hostmaster@domain.com
Webmaster@domain.com
Postmaster@domain.com
2.DNS verification
Verify domain name ownership by parsing the specified DNS record
For example, sr5jtl17ng5dfzjvx2lg9fxm90dygdps.domain.com-CName--- > s20150112110645.domain.com
The system will regularly check the CName record of sr5jtl17ng5dfzjvx2lg9fxm90dygdps.domain.com. If it can be detected and matches the specified value, the domain name ownership verification can be completed.
3. File verification
Verify the ownership of the domain name by creating the specified file under the root of the domain name
For example: create file irmvo302.htm file content NtdutxbskfhWvP3OffXW
The system will regularly attempt to access the http://xxx.domain/irmvo302.htm file. If the file can be accessed and the content matches, the domain name ownership verification can be completed.
