The Wildcard DNS Record is used to match requests for non-existent domain names. Wildcard DNS Record is specified by using a "*" as the leftmost label (part) of a domain name, e.g. *.example.com. This type of record allows all subdomains to share the same set of web content with a single DNS entry.
The Wildcard Record has the following look in your ClouDNS Control Panel:
| Host | Type | Points to: | TTL |
| *.hostname.com | A | ip.of.your.website | 1 Hour |
| *.hostname.com | AAAA | ipv6:of:your:web::site | 1 Hour |
| *.hostname.com | MX | your.mx.server | 1 Hour |
| *.hostname.com | TXT | TXT Record | 1 Hour |
| *.hostname.com | CNAME | example.com | 1 Hour |
| *.hostname.com | ALIAS | example.com | 1 Hour |
| *.hostname.com | WR | http://example.com | 1 Hour |
Let us explain it again, the wildcard DNS record is a kind of record that answers DNS requests for subdomains you haven't already defined. In other words, with *.yourdomain.com wildcard record, it won’t matter whether someone accesses your site through ww.yourdomain.com or wwwwww.yourdomain.com.
Go to your Control Panel and click on “Add new record”. Type, as follow:
Type: A, AAAA, MX, TXT, CNAME, ALIAS or WR
TTL: 1 Hour
Host: *
Points to: (resource you need to setup - IP/hostname/something else)
Note: A Wildcard Record can be added only for A (or AAAA), MX, TXT, CNAME, ALIAS or Web Redirect.
We are supporting Wildcard DNS records not only for the root domain name (example.com) but for the subdomains too. Example setup for the wildcard record *.sub.example.com:
Type: A, AAAA, MX, TXT, CNAME, ALIAS or WR
TTL: 1 Hour
Host: *.sub
Points to: (resource you need to setup - IP/hostname/something else)

Question: Is a Wildcard DNS record a bad practice?
Answer: Despite the claims by some SEO specialists, that using the wildcard DNS records may refer badly to your website rating, there isn’t any technical obstacle for using it. Moreover, many clients find this feature very handy and they take benefit of it all the time.
Question: What will happen if I have specified subdomains and a Wildcard DNS record also?
Answer: Wildcard records don't override existing records. For example, if you have some record for example.domain.com and wildcard record *.domain.com, the hostname example.domain.com won’t be covered by the Wildcard.
