Once logged in to your Control Panel, select your domain (if you have more than one) and scroll to the bottom of the page and select 'Change Nameservers':
You can then 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). The first two fields must be completed, as denoted by the asterisk.
Once you have added the new nameservers, select 'Update'. The nameservers will update within 24 hours of your request. To check this, you can select whois info on the change nameserver screen.
