Universal domain name resolution is a DNS resolution technique that allows you to prefix a wildcard as a subdomain name, and all subdomains matching that wildcard point to the same IP address or server. This is very useful for websites or applications that manage large quantum domains, because you can achieve uniform processing of all matching subdomains through a wildcard configuration.

The common universal domain name resolution wildcard is *, which can be combined with other subdomain parts, such as *.example.com. This will match all subdomains with example.com as the domain suffix.

For example, if you configure a universal domain name resolution *.example.com, then all subdomains such as sub1.example.com, sub2.example.com, sub3.example.com, etc. will be resolved to the same IP address.

Universal domain name resolution applies to the following scenarios:

1. Multiple subdomain name management: When you have large quantum domain names, such as personal blogs, internal enterprise applications, mobile applications, etc., using universal domain name resolution can simplify DNS management without having to configure DNS records separately for each subdomain name.

2. Flexibility: If your application generates many dynamic subdomains, such as user profile pages, API subdomains, etc., universal domain name resolution can handle these changes more flexibly.

3. Simplify configuration: For websites with multiple services or functions, the subdomain names of all related services or functions can be pointed to the same IP address through pan-domain name resolution, thus simplifying configuration and management.

To configure universal domain name resolution, you need to log into your DNS hosting provider's control panel and add a corresponding DNS record that associates the wildcard with the IP address you want to point to. Please note that caution is required when using universal domain name resolution, as all matching subdomains will point to the same location and may have some security and administration implications.

General steps for setting up universal domain name resolution:

1. Log in to the Domain Management Console: Log in to the domain management console where you registered your domain name. This could be a control panel provided by your domain registrar, such as GoDaddy, Namecheap, etc.

2. Navigate to DNS Settings: Find the DNS Settings or domain resolution Settings associated with your domain name. Typically, this can be found in the domain name Settings or DNS Settings options of the domain name administration console.

3. Add DNS Record: In the DNS Settings page, you need to add a universal domain name record. This is often referred to as an "* record" or an "asterisk record".

4. Configure a universal domain name record:

a. Select to add a new DNS record.

b. Enter an asterisk (*) in the host name or name field as a wildcard.

c. In the record type, select the appropriate record type, usually A record or CNAME record.

d. In the Destination or Value field, enter the IP address or destination domain name that you want to map to. This is where you want all your subdomains to point.

5. Save changes: Make sure you save your changes for the new pan-domain record to take effect.

6. Wait for DNS to propagate: Once you have saved a DNS record change, it takes some time for it to propagate among DNS servers around the world. This process can take anywhere from a few minutes to a few hours. During this time, you may see old resolution results until DNS propagation is complete.

Please note that the exact steps may vary depending on the domain registrar's interface design. If you're having trouble setting up pan-domain name resolution, consult your registrar's documentation or contact their support team for detailed guidance.
