Вопросы и ответы

DNS (Domain Name System) is the system and protocol that translates domain names to IP addresses and more. HTTP (Hypertext Transfer Protocol) is used to transfer webpages. Background: DNS. In a typical network, your computer contacts a local DNS nameserver to resolve domain names to IP ad- dresses.
The DNS over HTTPS protocol uses built-in application HTTPS standards to encrypt queries. This means better privacy and data protection. When DNS over HTTPS is enabled, Man-in-the-middle attacks are more or less useless. Due to encrypted DNS requests, a 3rd party observer cannot make sense of the data they spy on.
In Chrome's address bar, enter chrome://flags/#dns-over-https and set Secure DNS Lookups to Enabled. Relaunch your browser, and your DNS queries will be encrypted! Note that Chrome looks for OpenDNS IP addresses specifically.
DNS over HTTPS (DoH) is a protocol that encrypts DNS traffic by passing DNS queries through an HTTPS encrypted session. DoH can help improve online security and privacy and protect DNS queries from attacks.
The client sends the HTTP/HTTPS request to the server's IP address, and the server responds accordingly. In summary, DNS plays a crucial role in HTTP/HTTPS communication by resolving domain names to IP addresses, enabling clients to connect to the appropriate servers and access the requested resources.
