To switch nameserver addresses at Tucows you can log into your Domain Management Interface at Tucows or opensrs.com, and click the 'Name Servers' link. You will see a screen similar to this:

You only have to add the hostname of the Name Server. (ie: NS1.EXAMPLE.COM)  The IP address of the server is handled automatically. 


You can then enter the name servers provided by Ezoic ('Settings' > 'Nameservers' > 'View Instructions' in the Ezoic Dashboard) in the Nameserver fields. Once you have entered your Nameservers, click 'Save Configuration.' 


Please remember that name server changes can take 24 to 48 hours to propagate.
