        Chrome Net _ What is Internal DNS

The term "Chrome DNS" is used for a variety of technologies, but the most prominent one is "Chrome DNS". It was invented by Google, a shortening technology that replaces domain names on the Internet with one import. It transfers fast which is favorable for the user when he does not want much time to access the content of a website. Chrome DNS can also be used for security, privacy, and customization.

Service 

"Chrome DNS" is not just a type of service, but it is a technology used to change the domain name as an import to the Internet user of the web browser. It is available in Google's Chrome browser. When a user browses a domain name, Chrome uses DNS to locate the server and quickly directs them to that server. It reduces page loading time and increases browsing speed.

DNS 64

"DNS64" is a technology that provides an interface between IPv6 and IPv4. When your device tries to get an IPv6- aware address, but that website's server is on IPv4- only, DNS64 translates that IPv4 address to an IPv6 address. This ensures that communication can be established between IPv6 and IPv4 connections, allowing more extended Internet use.

confidentiality

Confidentiality refers to the practice of keeping sensitive information private and secure, limiting access to authorized individuals or entities. It ensures that sensitive data is only disclosed to those who have a legitimate need to know and that it is protected from unauthorized access, use, or disclosure. Confidentiality is crucial in various contexts, including business, healthcare, legal matters, and personal relationships, to maintain trust and integrity. Measures such as encryption, access controls, non-disclosure agreements, and privacy policies are commonly used to uphold confidentiality.

History 

To view DNS history in Chrome browser, follow these steps:

1. Open Chrome browser:Open Chrome browser already or open it in your device.
2. Go to the Web History page:** In the upper left corner of the browser, tap "Applications", and then select "History".
3. Select Website:In this search bar, select the website whose DNS history you want to view.
4. Select DNS Protocol:** Now, after selecting the website, you need to select the "DNS" protocol, which will display your DNS history.

Next, you can view the DNS history available there. can see. This will show you any website attempts with the previous DNS server.

How does DNS route traffic to your web application?

DNS (Domain Name System) plays a vital role in routing traffic to your web application. When you open a website or web application, the DNS server translates that website's domain name into its IP address. Next, your device communicates with the website or application's server using that IP address. 

This process takes place in the following steps:

1. Domain Name Locating: When you enter a website's domain name, your device or browser sends it to technically locate the website's DNS server.
2. DNS Request: Your device sends a request for information to its ISP or other DNS server.
3. Getting the answer from the DNS server: The DNS server returns the answer to the IP address of the website.
4. Communication Establishment: Your device communicates with the website's server at that IP address, after which the website's content is downloaded.

Through this process, the DNS server obtains the IP address of the website. Allows your device to communicate with the website.

How can you use chrome://net-internals/dns mobile devices?

As of my last update, accessing `chrome://net-internals/dns` on mobile devices, particularly on Chrome for Android or iOS, is not directly possible through the browser interface. This is because mobile browsers typically have a simplified user interface compared to desktop browsers, and they do not offer direct access to internal settings and debugging tools like `chrome://net-internals`.

However, if you need to troubleshoot DNS-related issues on a mobile device, you can use alternative methods such as:

1. Using Developer Tools: Some mobile browsers offer developer tools or remote debugging features that allow you to inspect network activity, including DNS resolution. You can connect your mobile device to a computer and use desktop Chrome's developer tools to inspect network activity remotely. 
2. Third-party Apps: There are third-party networking apps available on mobile app stores that offer similar functionality to `chrome://net-internals/dns` for monitoring DNS resolution and network traffic. These apps may provide detailed insights into DNS queries and responses on your mobile device.
3. Terminal Emulators: For advanced users, terminal emulator apps available on some mobile platforms (e.g., Android) allow you to access the device's command-line interface. From there, you can use commands like `nslookup` or `dig` to perform DNS lookups and diagnose DNS issues directly on the device.

Keep in mind that these methods may require additional technical knowledge and may not be as user-friendly as accessing `chrome://net-internals/dns` directly on a desktop browser.
