How to protect your privacy and Safety improve on the Internet
What is a DNS server?
A DNS server (Domain Name System Server) is a special server designed to provide human-readable Domain names into IP addresses. This conversion is necessary because Desktop and other network devices use IP addresses to communicate with each other, while humans tend to have an easier time remembering domain names like "example.com."
The DNS server works similarly to a phone book, in which human-readable names (domain names) are matched with the corresponding IP addresses are linked. If a user has a Website When someone wants to visit or access an online resource, their computer sends a request to the DNS server. The DNS server then looks up the associated domain name, finds the associated IP address and forwards the request. This allows the Desktop connect to the desired server and retrieve the requested information.
There are different types of DNS servers including authoritative DNS servers, recursive DNS servers and root DNS servers. Each of these servers has a specific function within the domain name system and helps ensure the performance and reliability of the Internet.
Why are DNS server hacks important for your online security?
DNS server hacks are important for your online security because they can undermine the trust and integrity of the domain name system on which the Internet is based. If a DNS server is compromised, it can lead to various security issues affecting both your Privacy as well as the security of your data.
Some of the possible consequences of a DNS server hack are:
- DNS-Spoofing or DNS cache poisoning: In this type of attack, hackers add fake Posts into the DNS server or cache to redirect users to fake websites. This may result in users unknowingly revealing sensitive information such as usernames, passwords or share credit card information with cybercriminals.
- Denial of Service (DoS) attacks: In some cases, hackers can deliberately overload DNS servers with a flood of requests to render them unusable. This may result in legitimate users not being able to access Websites and have other online resources they need.
- Malware distribution: Compromised DNS servers can be used to direct malware to users' devices by targeting them to malicious Websites redirect or download dangerous software.
To ensure your online security, it is important to be aware of the potential risks associated with DNS server hacks and take appropriate measures to protect your devices and data. This includes using antivirus software, updating operating systems and applications, checking the SSL Certificates of websites and the use of secure DNS services.

If the problem persists, try changing the DNS server. You can use one of the previously mentioned DNS servers or another trusted DNS service search. steps How to change the DNS server varies depending on the operating system and device. Here are some Instructions for common systems:
Windows: Open Control Panel, go to Network and Internet > Network and Sharing Center > Change adapter settings. Right-click your network connection and select “Properties.” Select “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties”. Select “Use the following DNS server addresses” and enter the desired DNS server addresses.
macOS: Open System Preferences and click “Network”. Select your network connection and click “Advanced”. Go to the “DNS” tab and click the “+” symbol to add new DNS server addresses.
Check firewall and antivirus software:
Sometimes firewall or antivirus programs can block traffic to the DNS server. Check your security settings and make sure DNS traffic is not blocked.
Contact your Internet Service Provider (ISP):
If all other steps fail, the problem could be with the ISP. Contact your ISP support to resolve possible network issues.
By following these steps, in many cases you can fix the problem when the DNS server is not responding. However, if the problem persists, consider seeking professional help to conduct a more detailed investigation and resolve the issue.

How does name resolution via DNS work?
DNS name resolution is a process that converts domain names into IP addresses to enable communication on the Internet. The process involves queries to DNS resolvers, root servers, TLD servers, and authoritative DNS servers to determine the associated IP address and forward it to the requesting device. This happens within milliseconds and enables fast and efficient Internet communication.
