Wildcard DNS records have specific rules

If you use a wildcard DNS record, then special rules apply to the creation of new DNS records that fall under that wildcard. 

With a wildcard DNS record, you ensure that every subdomain of your domain name is covered by your DNS record. 

  • Wildcard DNS record: *.ninefortwo.be
  • Consequence: every subdomain of ninefortwo.be falls under this wildcard (e.g. blog.ninefortwo.be)

Create your own exceptions for certain labels that should not be included. For example, if you create app.ninefortwo.be, it will not be covered by the above wildcard. 

A label is the bit before your domain name, separated by dots.

Beware if you use more than one label!

If you create a DNS record with multiple labels, the labels that are not explicitly created are implicitly added by our DNS platform. 

  • Example of DNS record with two labels: app.blog.ninefortwo.be
  • Consequence: blog.ninefortwo.be is also automatically created as an empty DNS record. But this is not shown in your DNS zone.

    Additional consequence: blog.ninefortwo.be is no longer covered by the wildcard.
    If you want blog.ninefortwo.be to still effectively point to a particular IP address, you have to add it yourself as an additional DNS record.
