Consider: changing nameservers may look different depending on your registrar, not exactly like in the screenshots below, but typical steps are listed here.

• Login to your domain name registrar. This is the place where you bought your domain.
• Look for the option to set your domain’s nameservers. Every registrar has a different way of doing this. However, in general, you can find the appropriate settings on the menu called Domain Management, or Domain Settings, or something along those lines.

• Go to [your domain name] —> Manage DNS. Select the Use my own nameservers option.
• You should see several fields, such as Nameserver 1 (primary nameserver), Nameserver 2 (secondary nameserver), that will most likely be filled with your hosting provider’s default nameservers.

• Enter the nameservers into the appropriate fields. For example, a nameserver that begins with ns1 should be put into the Nameserver 1 field, if it starts with ns2 to Nameserver 2, and so on.

Keep these tips in mind should there be any difference between the number of nameservers and the number of available fields:

• If your registrar provides you with four or more fields, while you need to change only two, enter the needed two, leaving the other ones empty.
• Your registrar may additionally ask for your consent to change the domain’s DNS settings.

Try to look for the registrar’s Help or FAQ page if you still cannot find the menu to set your nameservers.
