The chrome://net-internals/#dns Mobile page provides real-time insights into DNS queries and cached entries. It’s like having X-ray vision for your browser’s network interactions. From diagnosing connectivity problems to managing DNS cache, this tool is your trusty sidekick in the digital realm.

How do I access chrome://net-internals/#dns on mobile?

1. Open Google Chrome on your mobile device.

Step by Step Guide on chrome://net-internals/#dns Mobile:

Let’s delve deeper into each step:

1. Access the Tool: 

• Open Google Chrome on your mobile device.
• Type `chrome://net-internals/#dns` in the address bar.
• Press Enter to access the tool. This will take you directly to the DNS section of Chrome’s network internals page.

2. Explore the Interface: 

• The page you land on is divided into two main sections: the control panel and the events log.
• The control panel at the top lets you clear the host cache and view or export the DNS cache.
• The events log at the bottom displays real-time DNS events as they occur.

3. Monitor DNS Queries: 

• The events log at the bottom of the page allows you to monitor DNS queries in real time.
• Each event is timestamped and includes details such as the hostname, IP address, and whether the query was successful.
• This can be particularly useful for identifying problematic queries or hosts.

4. Analyze DNS Cache: 

• The DNS cache is a list of all the hostnames that your browser has resolved recently.
• You can view this list by clicking the “View host cache” button in the control panel.
• Each entry in the cache includes the hostname, its corresponding IP address, and the time-to-live (TTL) which indicates how long the entry will be kept in the cache.

5. Clear DNS Cache: 

• If you’re experiencing issues with a particular website or after changing your DNS settings, you might need to clear your DNS cache.
• To do this, click the “Clear host cache” button in the control panel.
• Remember that this will clear all cache entries, so your browser must resolve all hostnames again the next time you visit a website.

6. Troubleshoot Issues: 

• The chrome://net-internals/#dns mobile tool can be a powerful ally when troubleshooting network or website issues.
• For example, if a website isn’t loading, you can check the events log to see if there are any issues with the DNS query for that website.
• Similarly, if you’ve recently changed your DNS settings and are experiencing issues, you can clear your DNS cache and monitor the DNS queries to ensure they are resolved correctly.

Remember, while this tool provides a wealth of information, it’s also quite technical. Don’t be discouraged if you don’t understand everything right away. With practice and patience, you can use it to diagnose and resolve network issues like a pro!

DNS caching  Explained:

1. Purpose of DNS Cache:

• Imagine DNS as a phone book for the internet. It maps domain names to IP addresses.
• When you type a URL (e.g., lifewire.com), your browser asks your router for the IP address.
• The router consults its stored DNS server address and requests the IP address from the DNS server.
• The DNS server finds the IP address for lifewire.com, allowing your browser to load the website.

2. Why DNS Caching Matters:

• Public DNS servers exist, but having a local “phone book” (DNS cache) is faster.
• DNS caches store recent lookups, avoiding repeated requests to external servers.
• Each step in the lookup process (router, ISP, root DNS servers) has its cache.

3. How DNS Cache Works:

• Before your browser sends requests to the internet, it checks the DNS cache.
• If the domain name is in the cache, it retrieves the corresponding IP address.
• Otherwise, it initiates a new DNS lookup and updates the cache with the result¹.

4. Effects of DNS Cache Poisoning:

• DNS cache poisoning occurs when incorrect data enters the cache.
• It can lead to misdirected traffic or security risks.
• Regular cache flushing helps maintain accuracy⁴.

Remember, DNS caching keeps the internet running smoothly by reducing lookup times!
