Domain name verification is a process used to confirm the ownership or control of a domain name. Various methods are employed to ensure that the individual or organization claiming control of the domain is indeed authorized. Here are some common methods:
DNS TXT Records: This involves adding a specific TXT record to the DNS configuration of the domain. The record contains a unique code provided by the verifying entity, which can be checked to confirm ownership. For example, when setting up an SSL/TLS certificate, a Certificate Authority (CA) might require a TXT record to be added.
HTML File Verification: Some services require the creation of a specific HTML file with a unique code in the domain's root directory. When the service accesses this URL, it checks for the presence of the file to verify ownership.
Domain Control Validation (DCV): This method involves sending an email to an administrative contact listed in the domain's WHOIS information. The recipient must click a link in the email to confirm control of the domain.
HTTP/HTTPS File-Based Verification: Similar to HTML file verification, this method requires placing a specific file in a designated directory on the website. The verifying service checks if the file is accessible and contains the correct content.
Email Verification: Some services send an email to a verified email address associated with the domain. The recipient must respond to the email or click a verification link to confirm ownership.
API Verification: For automated systems, some services offer APIs that can be used to programmatically verify domain ownership.
For cloud services, platforms like Tencent Cloud offer various domain-related services that might require verification. For instance, when setting up a cloud load balancer or a content delivery network (CDN), domain verification might be necessary to ensure proper configuration and security. Tencent Cloud provides detailed guides and support for domain verification processes, helping users to securely manage their domain resources.
