Why run your own DNS?
Because the Internet is built upon IP addresses, without DNS, the Internet would become far less accessible. DNS allows visitors’ computers to find your server without them having to navigate strictly by IP address.
When should I use flush DNS?
Your system holds the IP address of named sites… When you do a ipconfig /flushdns, your system clears the cache of name to ip entries and reloads them from the connected DNS server. Unless you’re on old versions of Windows, it means that the website operators messed up.
What is DNS advantages and disadvantages?
DNS allows users to categorize and archive search terms without needing to remember IP addresses. All the domains are converted into IP addresses when the name is given to the search engines. Therefore, you don’t need to memorize IP address for each and every site that you access frequently.
What is private DNS mode mean?
This means no tracking of your whereabouts online and no third-party ads using your data. Many support DoT and DoH so your data is encrypted. Prior to Android 9, the only way to use private DNS servers was to configure them for individual saved Wi-Fi networks or use a local VPN.

What are the benefits of DNS caching?
Ultimately, the DNS enables human users to keep track of more web pages and to access them as required, and DNS caching expedites the DNS lookup process to more quickly resolve a domain name to an IP address when the OS has visited a web page before.
What benefits does the Domain Name System DNS provide?
The benefits of DNS are that domain names:can map to a new IP address if the host’s IP address changes.are easier to remember than an IP address.allow organizations to use a domain name hierarchy that is independent of any IP address assignment.
