I contact you as I'd like to know what is the best in my situation. I plan to get one main server that will host all my customers with a full paid Virtualmin licence unlimited. Then I'm going to setup two tiny cloud server to be used as main and secondary DNS servers. Do I need to buy a Virtualmin licence for these two servers too ? or I can go with the GPL version ? considering that DNS records will be handled by my main hosting server that will push them to these two tiny DNS servers ? I want to do it this way as I got lot of issues to setup successful DNS system with Virtualmin/webmin in past and so wants to be able to debug that out of my main hosting system !
Thanks for your advices,
