Once you have setup DNS service for your domain name, you need to modify the domain name's Name Servers to the ones specified by Registr. UANIC DS (www.uanic.name). See details
Do not be confused when you encounter errors such as No NS A records at nameservers while using some DNS Tools like DNSReport.com. This does not indicate an error and will not affect the resolution of your domain name or any Resource Record created by you.
