Step 1: Log in to your OVH Control Panel, click 'Domains' in the services bar on the left-hand side, then choose the domain name concerned. Next, go to the 'DNS Servers' tab.
The table that appears will show the DNS servers currently set with OVH for your domain name. Several DNS servers may be listed, each with their own row in the table.
Step 2: To start editing your DNS servers, click the 'Modify DNS servers' button as seen above.
In the text fields, enter the custom name servers generated for you by Ezoic (these can be found under 'Settings' > 'Site Integration' > 'Name Servers' > 'View Instructions' in your Ezoic Dashboard).
Once you have entered this information, click 'Apply configuration'. The statuses for the DNS servers will then update in the table, showing the new information that you have just provided.
Step 3: Once you have made the required changes, you will need to wait for them to become fully effective.
The change made on the OVH side needs to be taken into account by the organisation that manages your domain name extension (registry). You can track the progress for this in your OVH Control Panel by going to the 'Domains' section in the services bar on the left-hand side, then 'Ongoing operations'. Once the change has been taken into account by the organisation managing your domain name extension, you will need to wait for a maximum of 48 hours for the changes you have made to fully propagate.
