Today we'll talk about what DNA is, including the DNS working principle
and the reason for DNS Leak, which causes your online information such
as email, Facebook, Twitter, tinder, and even online bank hackedbecome.
DNS (Domain Name System) is a distributed database that maps domain
names and IP addresses on the World Wide Web. The Internet address is a
numeric IP address, and the domain name is easy to store. This
allows users to access the Internet without having to remember the IP
strings that can be read directly from the computer.
The DNS working principle, for example, a domain name: abc.com, is
to display this HTTP service. If you want to access the website,
you must fix it.First, deploy it to a Web server through a dedicated DNS
server at the domain registrar under the fixed IP address
211.221.1.xxx, and receive the domain name through the Web server.
The domain name abc.com is assigned to this server. Then enter the
domain name abc.com to access the content of the site.This completes the
entire domain name resolution process.
There are several main reasons for a DNS leak, usually due to a
configuration error, a VPN or network, or Microsoft Windows. This may
also be due to more malicious incidents, eg.For example, an attacker
controls your router.
The main factors that cause DNA leaks:
* Your operating system may have features that interfere with DNS traffic.
* Your DNS is configured to use a DNS server that is not controlled by VPN.
* An incorrect network configuration resulted in a DNS request leak.
* Do not support IPv6 address.
How do I avoid DNA leaks?
With a VPN !!
Although we are writing this article on the assumption that you should already use a VPN, it is worth repeating this problem. A VPN service can easily hide your traffic and hide IP addresses to prevent DNS leaks.
