Your web host should tell you the IP addresses for your name servers if you are planning to register your own name servers. Steps on how to register your own name servers can be found here:
How do I register my own name servers (glue records)?
Glue records associate a hostname with an IP address. They are needed when you want to set your domain's name servers to a hostname that is a subdomain of your domain.
To create your own name servers for a domain registered at Dynadot, please follow these steps:
Select "My Domains" from the left-side menu bar and click "Name Servers" in the drop-down.
Click on the "Register Name Server" button in the top right corner of the page.
Enter the host name (ns1.mydomain.com, for example) in the text box labeled "Host Name".
Enter the IP address for the name server in the text box labeled "IP Address".
Press the "Register Name Server" button to save your changes.
You can submit either an IPv4 or IPv6 IP address (except .WS domains, which do not support IPv6 addresses). You can also set multiple IP addresses. Please remember to configure your name servers with the corresponding A records. This would be done in your hosting control panel rather than your Dynadot account.
Your settings should look similar to what is shown below:
NOTE: Custom domain name servers (glue records) can only be registered at Dynadot if the domain is registered here. If you are trying to register a name server for ns1.mydomain.com, for example, and mydomain.com is registered with a third party, you would not be able to create glue records with Dynadot.
If, however, your web host has only given you a list of name servers to use, then most likely you will need to set your domain to use their name servers. Here are the steps to set your domain to use your web host's name servers:
How do I set my name servers for my domain?
To set your name servers, please follow these steps:
Select "My Domains" from the left-side menu bar and click "Manage Domains" in the drop-down.
Check the box next to your domain name(s) and click on the "Action" button.
Choose "DNS Settings" from the "Action" list.
On the DNS page, select the "Name Servers" setting from the top drop-down menu.
There are two ways to set name servers: - If you are adding new name servers, select "Enter new or existing Name Servers" from your list of choices and enter your new name servers in the provided fields. - If you are using existing name servers, move down to the "Select from your Name Servers" option and choose the name servers from your existing list.
Press the "Save Name Server" button to save your changes.
Please be aware that it might take some time for your name server changes to propagate.
Alternatively, you can also set your Name Servers when transferring your domain. To do so, while your item is in the cart, please click on the hardware icon. It will prompt you through a short two step wizard and guide you through the set up process.
