How to set up Wildcard Subdomains / DNS
If you need to set up a wildcard subdomain, that can be done in your hosting cPanel account. A wildcard DNS record is a record that matches requests for non-existent
domain names. A wildcard DNS record is specified by using the "*"
symbol to create a record for *.yourdomain.com.
How to create a Wildcard Subdomain in cPanel
1) - cPanel makes creating a wildcard subdomain quick and easy. First, log into your cPanel account and click on Subdomains.
2) - Next, in the "subdomain" field just put a *. The *
is often used to signify a wildcard symbol and it does in cPanel as
well.
Make sure that the Document Root stays as "public_html".
3) - Then click on "Create." A confirmation page will appear, click "Go Back" and confirm the subdomain was created.
That is it! Your account is now set up for wildcard subdomains.
Depending on the reason you've set up the Wildcard Subdomain, a
.htaccess modification may be needed. |
