What is Wildcard DNS Record?

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

Why do you need a Wildcard record?

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.

How to create a Wildcard record?

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.

FAQ

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.
