The use of a Private DNS server is extremely useful. Today, we’ll look at why it’s important and how to put it into practice. But first, let’s go through what it’s all about.
Private DNS server: What does it mean?
As the name implies, a Private DNS server appears to be something personal. It serves as a conduit between your network and the Domain Name System server, preventing data from being intercepted. It’s a DNS network that isn’t connected to the public DNS. Consider it a little private library with a small book collection. This has both benefits and drawbacks. Yes, certain types of books will be unavailable to you. However, there is one advantage: no one will know what you are reading because your library is private.
Private is also known as DNS over TLS (Transport Layer Security) or DNS over HTTPS (Hypertext Transfer Protocol Secure). This is because all DNS queries are encrypted when using DoT (DNS over TLS) or DoH (DNS over HTTPS). As a result, suspicious third parties will have a much more difficult time snooping on your web activity.
A Private DNS server offers a plethora of advantages. We’ll simply look at one aspect of them. Here they are:
- Additional DNS zones and records. You can host as many DNS zones, and DNS records as your server can support. You will be able to use as many DNS records as you require (A, AAA, SOA, PTR, MX, TXT, CNAME, etc.).
- It ensures your safety! This is arguably the most crucial advantage of the Private DNS server. If you use a public DNS server, you may be more vulnerable to DoS and DDoS attacks. This is exceedingly unlikely to happen if you use a Private Domain Name System server.
- Almost all premium services are available. Yes, nearly all premium options are provided on the Private Domain Name System server. It could, for example, have Secondary DNS and Dynamic DNS.
How can you implement a Private DNS server?
Setting up your own Private DNS server is simple. However, the technique varies based on your device (computer, smartphone, Operating System, etc.). To recap, you must configure a DNS address on your device to activate Private DNS. Furthermore, having direct links to a third DNS server with DoT or DoH capabilities would be excellent.
Let’s do a review. First, a Private DNS server is really advantageous. It helps to improve security. In addition, with it, you have more DNS zones and records. As a result, installing a Private DNS would be beneficial to businesses. Its employees are safe, the network is secure, and criminal actors will be unable to “probe” or “scout” their network or communications. Furthermore, Private DNS can operate with little or no management once correctly configured. So having it implemented is worthwhile.
