1. Check your internet connection | Before using Chrome net internals DNS, make sure your internet connection is working properly. If there's an issue with your connection, it could be the cause of the DNS issue. |
2. Access the Chrome net internals DNS page | Open the Chrome browser and enter "chrome://net-internals/#dns" in the address bar to access the Chrome net internals DNS page. |
3. Check the DNS status | Under the "DNS" tab, check the "Status" column to see if the DNS resolution process was successful or if there were any errors. If there was an error, the status will indicate "Failed" or "Error". |
4. Clear the DNS cache | If you suspect the issue is related to cached DNS information, click the "Clear host cache" button located under the "DNS" tab to clear the DNS cache. |
5. Check the DNS lookup time | The "Lookup time" column under the "DNS" tab shows how long it took to resolve the DNS query. If the lookup time is longer than usual, it could indicate an issue with the DNS server. |
6. Analyze socket connections | Under the "Sockets" tab, you can analyze socket connections to determine if there are any issues with the connection between the browser and the DNS server. Look for any connections with a status of "Reset" or "Timeout". |
7. Check DNS server settings | If the issue persists, check your DNS server settings. Under the "Internals" tab, navigate to "DNS" and select "Custom". Verify that the correct DNS server addresses are entered. |

What Is DNS Resolution Process?
The Domain Name System (DNS) is a protocol used to translate
human-readable domain names into IP addresses that computers use to
communicate with each other over the internet. When you enter a
website address into your browser's address bar, your computer sends a
request to a DNS server to resolve the domain name to its
corresponding IP address. Here is a general overview of the DNS
resolution process:
Step | Description |
---|---|
1. Your computer sends a DNS query to a DNS resolver | When you enter a domain name into your browser, your computer sends a query to a DNS resolver to translate the domain name into an IP address. The DNS resolver is typically provided by your Internet Service Provider (ISP), but you can also use third-party DNS resolvers like Google DNS or Cloudflare DNS. |
2. The DNS resolver sends a request to the root DNS server | If the DNS resolver doesn't already have the IP address for the requested domain name, it sends a request to the root DNS server. The root DNS server maintains a database of all top-level domain names (such as .com, .org, .net, etc.) and their corresponding DNS servers. |
3. The root DNS server responds with the IP address of the top-level DNS server | The root DNS server responds to the DNS resolver with the IP address of the top-level DNS server responsible for the requested domain name's top-level domain (TLD). For example, if the requested domain name is example.com, the root DNS server would respond with the IP address of the .com DNS server. |
4. The DNS resolver sends a request to the top-level DNS server | The DNS resolver sends a request to the top-level DNS server for the IP address of the domain name's authoritative DNS server. |
5. The authoritative DNS server responds with the IP address of the requested domain name | The authoritative DNS server for the requested domain name responds to the DNS resolver with the IP address of the domain name's web server. |
6. The DNS resolver caches the IP address | The DNS resolver caches the IP address for a period of time to speed up future DNS lookups. If the IP address changes, the DNS resolver will need to update its cache accordingly. |
7. Your computer connects to the web server | With the IP address of the web server, your computer can now connect to the web server to retrieve the requested web page or content. |
This is a basic overview of the DNS resolution process, and there are
many factors that can affect the speed and reliability of DNS lookups,
including network latency, DNS caching, and DNS server
availability.
What Is DNS Spoofing And Security?
DNS spoofing, also known as DNS cache poisoning, is a type of cyber
attack where a malicious actor intercepts and alters DNS queries in
order to redirect users to a fraudulent website or steal sensitive
information such as login credentials.
DNS spoofing can be particularly dangerous as it is often difficult
for users to detect. The spoofed website may look identical to the
real website, making it difficult for users to distinguish between
the two.
To protect against DNS spoofing attacks, it is important to take
several security measures, including:
Security Measure | Description |
---|---|
Using Secure DNS Servers | Utilize secure DNS servers like Google DNS or Cloudflare DNS to protect against DNS spoofing attacks. |
Enabling DNSSEC | DNSSEC is a security protocol that authenticates DNS queries, preventing DNS spoofing attacks. |
Keeping Software Up to Date | Regularly update your operating system and web browser to safeguard against known vulnerabilities exploited in DNS spoofing attacks. |
Using a VPN | Enhance online privacy and security by employing a VPN, which encrypts internet traffic and safeguards against DNS spoofing attacks. |
Being Cautious with Personal Information | Exercise caution when entering personal information on websites. Verify the website's URL matches your intended site, and look for secure connection indicators like a padlock icon. |
Overall, DNS spoofing is a serious security threat that can lead to
identity theft, financial loss, and other serious consequences.
Taking steps to protect against DNS spoofing attacks can help keep
you and your information safe online.
FAQs
Q: What's the point of the DNS cache in Chrome Net Internals
DNS?

you don't have to wait for a new search every time.
Q: Why mess with the DNS resolver cache in Chrome Net Internals
DNS?
A: Changing the DNS resolver cache can be handy for fixing
network issues or getting around certain internet restrictions. For
instance, you might need to tweak it to access a site blocked by
your internet provider or to solve problems connecting to a specific
website.
Q: Is it safe to fiddle with the DNS resolver cache in Chrome Net
Internals DNS?
A: Tinkering with the DNS resolver cache can cause trouble
with your internet connection or specific websites. So, it's best
left to those who know their way around network stuff and
troubleshooting.
Q: Can I use Chrome Net Internals DNS on my phone or tablet?
A: Nope, Chrome Net Internals DNS is more of a computer
thing. But don't worry! There are other tools and apps for phones
that can help fix DNS issues.
Q: What's DNS, and why does it matter?
A: DNS stands for Domain Name System. It's like the phonebook
of the internet, turning website names into actual addresses. DNS is
crucial because it lets you reach websites without remembering
complicated numbers.
Q: What are common issues with DNS?
A: Sometimes, websites load slowly, show DNS errors, or won't
connect. These hiccups can happen because of wrong DNS settings,
cache problems, internet issues, or troubles on the server side.
Q: How does DNS caching affect website updates?
A: DNS caching might delay website updates. Even after a site
changes, your computer or network might still look at the old
address. To fix this, website owners can set a shorter time for DNS
records to refresh.
Q: What are some common DNS server options and how do they
differ?
A: There are several DNS server options available,
including:
DNS Servers Type | Description |
---|---|
ISP DNS servers | These are the DNS servers provided by your internet service provider. They are generally the default option and are used by most users. They are often optimized for local performance but may not provide the best security or privacy. |
Public DNS servers | These are DNS servers that are available to the public and are operated by third-party companies such as Google, Cloudflare, and OpenDNS. They are generally faster and more secure than ISP DNS servers but may not be optimized for local performance. |
Private DNS servers | These are DNS servers that are set up and maintained by a user or organization. They are generally used for security and privacy reasons and can provide more control over DNS resolution. |
Q: What's a DNS resolver?
A: A DNS resolver is like a detective for your computer. It
looks up domain names you type in your browser, finds their secret
numbers (IP addresses), and connects you to the right website.
Q: How can I check my computer's DNS resolver?
A: You can use a fancy computer command or online tools
like "dnsleaktest.com" to see which DNS resolver your computer is
using. It's like peeking behind the scenes!
