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.
