How to quickly and safely configure external DNS with Slave DNS manager extension on Plesk
As DNS is the necessity for network communications, the DNS infrastructure must be highly available. To achieve the essential redundancy, you need to have at least two DNS servers. If something is wrong with one DNS server, the other one takes over immediately.
In Plesk, you can configure an external DNS server with several extensions. Let's learn how to accomplish this with Slave (Secondary) DNS Manager extension.
In comparison to other solutions, the Slave (Secondary) DNS Manager has its own infrastructure, supports different OS'es if they have BIND. If something goes wrong, you can always access log files and solve the issue by yourself. It has no limits for creating NS'es, and it is attractive for hosters having more than 1000 domains.
