What Is Optus DNS Server?

The Optus DNS server is a crucial component of the Optus network infrastructure. DNS stands for Domain Name System, which is responsible for translating domain names into IP addresses. When you enter a website address in your browser, the DNS server is responsible for resolving that domain name to the corresponding IP address where the website is hosted.

Why is DNS important?

DNS plays a vital role in how the internet works. Without DNS, we would have to memorize and enter IP addresses manually to access websites, which would be inconvenient and impractical.

Optus, one of Australia’s leading telecommunications companies, operates its own DNS servers to ensure efficient and reliable internet connectivity for its customers. By using their own DNS servers, Optus can optimize network performance and provide enhanced security features.

How does Optus DNS work?

When you connect to the internet through an Optus network, your device automatically receives the IP address of the Optus DNS server. This server acts as an intermediary between your device and websites you want to visit.

DNS Resolution Process

  1. Your device sends a request to access a specific website.
  2. The request is forwarded to the Optus DNS server.
  3. The Optus DNS server checks its cache for a previously resolved IP address for the requested domain name. If found, it returns the corresponding IP address immediately.
  4. If not found in cache, the Optus DNS server forwards the request to other authoritative servers on the internet until it obtains the correct IP address.
  5. The obtained IP address is returned to your device.

Advantages of using Optus DNS server

Optus DNS server offers several advantages:

  • Improved Performance: By using Optus DNS servers, you can experience faster website loading times and reduced latency.
  • Enhanced Security: Optus DNS servers include security features such as blocking access to malicious websites and preventing phishing attempts.
  • Reliability: Optus operates a robust network infrastructure, ensuring high availability and reliability of their DNS servers.
  • Caching: The Optus DNS server caches previously resolved domain names, reducing the time taken to resolve frequently accessed websites.

How to configure your device to use Optus DNS server?

The process of configuring your device to use the Optus DNS server may vary depending on the operating system. Here are general steps to get started:

Windows:

  1. Go to Control Panel > Network and Internet > Network and Sharing Center.
  2. Select your active network connection (Ethernet or Wi-Fi).
  3. Click on “Properties” then select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”.
  4. Select “Use the following DNS server addresses” and enter the primary and secondary Optus DNS server addresses provided by your ISP.
  5. Click “OK” to save the changes.

MacOS:

  1. Go to Apple menu > System Preferences > Network.
    Select your active network connection (Ethernet or Wi-Fi).
    Click on “Advanced” and go to the “DNS” tab.
    Click on the “+” button to add a new DNS server.
    Enter the primary and secondary Optus DNS server addresses provided by your ISP.
    Click “OK” to save the changes.

Remember to consult Optus support or your ISP for specific instructions on configuring your device to use their DNS servers.

In conclusion

The Optus DNS server is an integral part of the Optus network infrastructure, responsible for translating domain names into IP addresses. By utilizing their own DNS servers, Optus can offer improved performance, enhanced security, reliability, and caching capabilities.

Configuring your device to use the Optus DNS server can help optimize your internet experience.
