What is a catch-all (wildcard) subdomain?

If you want a browser to be able to access your site regardless of the subdomain requested, such as www.example.com or example.com, a catch-all wildcard subdomain can help. This feature directs all traffic to a single location, making it easier to manage and reducing the chance of errors due to typos.

Benefits of Catch-All Wildcard Subdomains

Simplified Domain Management: Manage multiple subdomains with one record.
Reduced Error Risk: Catch common typos or unrecognized subdomains.
Cost-Effective Solution: Saves on additional domain purchases and configurations.

How It Works

A catch-all wildcard subdomain uses a special DNS record, such as *, to route all subdomains to the main domain. For example:

*.example.com routes www.example.com, example.com, and mail.example.com to your main site.

When to Use It

For Temporary or Test Subdomains: Quickly set up additional domains without registering each one separately.
To Catch Common Typos: Ensure users land on the correct page even if they miss a part of the domain name.
For Single-Property Domains: Ideal for websites with a single location but multiple potential subdomains.

Limitations

Cannot Be Used for Subdomains Requiring Specific Configurations: If your hosting provider requires specific subdomain configurations, a catch-all may not be suitable.
May Not Work With All Hosting Providers: Compatibility varies depending on the platform you use.

Examples

Example 1:
- Main Domain: example.com
- Catch-All Record: *.example.com
- Result: Both www.example.com and example.com point to your main site.
Example 2:
- Main Domain: mail.example.com
- Catch-All Record: *.mail.example.com
- Result: Subdomains like user.mail.example.com route to the main domain.
