    HTTPDNS:Manage domain names

    Last Updated:Jun 03, 2026

    Add domain names for resolution in the HTTPDNS console and manage existing domain name rules.

    Add a domain name

    1. Log on to the EMAS console.

    2. In the left navigation pane, choose Resolution Management > Add Domain Name.

    3. Click Add Domain Name. Enter a valid domain name or wildcard domain name, and then click OK.

      Examples:

      1. Specific domain name: www.example.com or a.example.com.

      2. Wildcard domain name: *.example.com. Matches subdomains like a.example.com, b.example.com, and a.b.example.com.

      3. Top-level domain wildcards (*.com, *.cn, *.net) are not supported.

    Note

    • HTTPDNS supports all domain names, including those from Alibaba Cloud DNS, third-party registrars, and international registrars. International domain names must comply with applicable laws and regulations.

    • Changes take effect within approximately one minute.

    • Each account can have up to 200 domain name rules.

    Resolve-all mode and blacklist for DoH

    DoH lacks built-in authentication and often applies system-wide, making it impractical to whitelist every domain. HTTPDNS provides a Resolve all domain names option and a blacklist for fine-grained access control.

    DoH resolution matching rules:

    • Requests are first matched against the domain name list (whitelist), and then against the blacklist.

    • If Resolve all domain names is set to No, only domain names in the domain name list are resolved.

    • If Resolve all domain names is set to Yes, the domain name list is ignored and all domain names are resolved.

    • The blacklist takes priority over the domain name list. If a domain appears in both, resolution is denied.

    Important

    • Some libraries probe DoH availability using specific domain names. If you use a whitelist, add these probe domains to ensure DoH works correctly.

      • Qt WebEngine and Electron use www.gstatic.com

      • The CEF framework and Chrome browser use google.com

    Delete a domain name

    In the domain name list, click Delete next to a domain name, then confirm.

    Note

    • Once deleted, HTTPDNS stops resolving domain names that matched the rule.

    • Deleted domain names can only be recovered by re-adding them.

    View domain name data

    In the domain name list, click View next to a domain name to see its resolution data.

    Note

    Domain name resolution data is available on a T+1 basis.
