The purpose of a Private DNS server
A Private DNS server, as the name suggests, is something unique. They’re Private DNS networks that aren’t connected to the public DNS. Consider it a personal library with a limited number of books. This has both advantages and disadvantages. However, if you want to read a specific kind of book, you will be unable to do so. Nevertheless, there is one advantage: no one will know what you are reading because your library is private.
Elements of Private DNS server
Two fundamental terms should be learned in order to better understand Private DNS:
- TLS is the first one. Transport Layer Security (TLS) is one of the most extensively used security protocols for encrypting, authenticating, and verifying data integrity. The main purpose of TLS is to secure two-way communication between a client and a server on one side and a server on the other. Furthermore, Transport Layer Security (TLS) has completely supplanted SSL (Security Socket Layer). Although the SSL protocol hasn’t been secure in a long time, people are still hunting for it, so you’ll hear about it for a little longer.
- HTTPS is the second one. It is a more secure version of HTTP and stands for Hypertext Transfer Protocol Secure. The encryption codes or session keys generated by HTTPS must be certified by a third-party authority. Due to the system’s security, users without authorization will not be able to access the information of others. How? It encrypts HTTP requests and answers with TLS (or SSL in the past). If a third party had access to the information exchanged, it would be unintelligible. The message will appear to be made up of a jumble of characters.
What are the advantages?
A Private DNS server is extremely useful. Why? Because it provides you with security. If you use a public DNS server, you may be more vulnerable to DoS and DDoS attacks. However, if you use a Private DNS server, this is extremely unlikely to occur. The Departments of Transportation and Health is in charge of ensuring this. They encrypt data sent between your network and the DNS server, preventing third parties from intercepting it.
How can you implement it?
If you want to set up a Private DNS server, it’s not too difficult. However, the process varies depending on your device (computer, smartphone, operating system, etc.). To sum it up, in order to enable Private DNS, you must configure a DNS address on your gadget. Furthermore, it would be best if you had direct connections to a 3rd DNS server that supports DoT or DoH features.
In conclusion, we can say that Private DNS is absolutely beneficial. Why do you need to use it? Because it gives you extra security. So, don’t waste any more time, and implement it!
