Where is the domain name REGISTERED?
A domain name can be registered with one company and hosted by another. The company where the domain name is registered is called the registrar of that domain name. Only the registrar can appoint nameservers for a domain name. In most cases, the registrar will give you access to change them through their control panel. If Register.eu is your registrar, you can change your nameservers following this tutorial.
Which nameservers the domain name is configured to use?
You can find out both your registrar and your nameservers via a whois check. There are multiple free whois databases online.
The default nameservers of Register.eu are:
Those could be customized. Other domains/aliases could point to the same IPs which would effectively mean the above nameservers are used. If there is a possibility your web developer or other customized them for you, you can check if your nameservers resolve to the same IP addresses as the nameservers above.
After a change of nameservers, a propagation period takes place where a NS check may return false values. The propagation time is usually up to 24 hours, occasionally reaching 36.
You can only manage the DNS settings of your domain name through the control panel if you use the Register.eu nameservers.
