I have more than 50 domains right now. Since I’ve already stopped domain names I am thinking of making mini sites with those domains. The domains are registered in various domain registrars ranging from Namepros, Namecheap, Godaddy, Registerfly, Moniker and Creativeon. Managing so many domains on different registrar interfaces is a hard work.So, I am looking if there is some way to own DNS server. Concentric Total Solution let users have their own DNS server with high security and easy-to-use Interface. Its DNS Manager allows user to configure all components of DNS server service in near real time.And the price is dirt cheap, .20$ per month per domain. They also have groupware software. Groupware software consists of personal and team collaboration software tools which are fully integrated with users email and hosting account.
