A wildcard DNS record is a catch all record in a DNS zone that will match all non-existent requests for a domain name. For example if someone visits friend.yourdomain.com but you did not create friend.yourdomain.com the wildcard will forward that user to www.yourdomain.com.
If you need to setup Wildcard DNS for your domain, please contact our Technical Department with your account details and we will set it up for you.
