Protect: secure DNS requests
DNS hijacking risks
In order to access an internet site, you need to know the IP address. But it's easier for users to remember domain names (the letters comprising the site address) than to remember the string of numbers that make up the IP address. DNS is a widely-used system for getting the IP addresses that correspond to domain names.
When a user enters a website address, this is what happens:
- The browser sends a request specifying the domain to a special DNS server.
- The DNS server returns a response with the appropriate physical IP address.
The lack of encryption means that:
- The internet provider or network administrator can find out which sites a user is visiting.
- Attackers can tamper with the response from the DNS server and redirect the user to a malicious site. For example, instead of going to a bank's website, a user might end up on a fake site that steals passwords.
DNSCrypt technology in Yandex Browser
This is how DNSCrypt technology works:
- DNSCrypt encrypts requests sent from your computer using elliptical cryptography.
- Encrypted requests are send to the DNS sever, which supports the DNSCrypt protocol.
- The DNS server then sends the encrypted IP address to your computer.
Enabling encryption of DNS requests
- Click .
- Go to the Protect tab at the top of the page.
- In the Secure connection section, select Use DNS server with DNSCrypt encryption.
- Choose a DNS server from the drop-down list.Примечание. We recommend selecting the Yandex DNS server.
