I would like to ask what is the benefit of having more than 2 dns servers. We have dedicated server RHL 7.3 and we set it up as a dns server having ns1 and ns2 but my boss ask me if we could add additional nameservers as other company have. From where can i get the additional dns servers so that i will ahve a total of 4 ns. Should i get this with the same Dedicated server provider or should i get it anywhere else.. i heard that there is also something like public DNS, is that safe to use? Thanks Guys for your experties!!!

Regards,
Charlzmike
