How to change your router's DNS settings for faster browsing

Changing the DNS addresses in your home router can reduce name-lookup delays and give you more control over filtering. It affects every device using the router, including laptops, phones, TVs and smart-home equipment.

Speed gains are not automatic. If your internet service provider already operates a nearby, reliable resolver, a public resolver may make little difference. A slow resolver can make the first visit to a website feel sluggish even when bandwidth is plentiful.

The practical process is straightforward: identify the resolver supplied by your NBN or fixed-wireless provider, replace it with a trusted pair of DNS addresses, and test the result without altering other network settings.

What DNS actually changes

DNS translates a website name such as example.com.au into an IP address that your device can connect to. Your router normally forwards these requests to the DNS resolver configured by your internet provider, which then retrieves the address from the wider DNS network.

The distance and load of that resolver matter, particularly for households in regional Australia. A cached answer can return quickly, while an uncached lookup may take longer. Reading network security news can also help explain changes affecting Australian broadband providers and connected equipment.

Choosing a suitable DNS resolver

Choose a resolver based on speed, privacy policy, filtering and reliability. Common choices include Cloudflare at 1.1.1.1 and 1.0.0.1, Google at 8.8.8.8 and 8.8.4.4, and Quad9 at 9.9.9.9 and 149.112.112.112. Quad9 also blocks known malicious domains.

Using a resolver outside Australia does not automatically mean slower responses because many public DNS services use global anycast networks with nearby routing points. Test the available options rather than assuming the closest office is fastest.

Changing resolvers does not make your connection anonymous. Your internet provider can still observe network traffic and may retain connection logs. For organisations covered by the Australian Privacy Act 1988 and the Australian Privacy Principles, resolver selection should also fit the organisation’s privacy and data-governance obligations.

Accessing your router controls

Open a web browser on a device connected to the same home network and enter your router's administration address. Common addresses include 192.168.0.1 and 192.168.1.1, but the manufacturer's manual or Australian internet provider app should identify the correct one.

Sign in with the administrator credentials. If the router was supplied by Telstra, Optus, iiNet, TPG or another Australian provider, the default details may be printed on the device. Record the current DNS settings before making changes so they can be restored if necessary.

Replacing the current DNS addresses

Look for a section named Internet, WAN, DNS Server or External DNS. Enter the two chosen resolver addresses in the appropriate fields. Some routers label them as primary and secondary DNS, while others ask for IPv4 and IPv6 addresses separately.

If the router provides DNS over HTTPS or DNS over TLS, enable it only when it is compatible with the selected resolver. Check the router's DHCP settings as well: the DNS server supplied to connected devices should normally match the new WAN resolver.

Review features that depend on the provider's DNS before saving. These can include parental controls, automatic device blocking, dynamic DNS records, home-security subscriptions or special local hostnames. Save the configuration and allow the router to restart when prompted.

A practical DNS change checklist

Before applying the configuration, work through this short checklist:

• Record the existing DNS addresses and administrator credentials.
• Use two reliable addresses from the same resolver service.
• Check whether IPv6 receives its own DNS configuration.
• Confirm that parental controls and security filtering still work.
• Apply the change during a quiet period to make troubleshooting easier.
• Test several websites rather than judging one page load.
• Keep the router firmware updated and the administrator password unique.

After saving, reconnect a phone or laptop and visit a site that is not already open in the browser. A DNS lookup test can reveal whether the new resolver responds correctly. If everything works, the old DNS addresses can be removed from your notes once you are confident.

Fixing common connection problems

If the internet stops working, check the router's WAN status and confirm that it still has an IP address, gateway and DNS configuration. Incorrect manual settings can prevent DHCP, VPN or IPTV services from connecting. Restore the original addresses if necessary, update the router firmware and try again.

Some devices may continue using their previous resolver because they cache DNS results or have private DNS enabled. Android's Private DNS setting, browser secure DNS and certain VPN profiles can bypass the router entirely. For a business website, coordinate the change with whoever manages its hosting and domain records; providers offering small business website builders should be able to confirm that the website's hostnames remain unchanged.

Keeping the change secure

When comparing a new network security appliance or Synology NAS, check whether it can forward DNS for local devices. Independent network product reviews and Australian retailer listings on Amazon.com.au can help with compatibility, warranty and local availability. Avoid buying unnecessary hardware when the existing router supports the required settings.

Keep remote administration disabled unless it is protected by a VPN, use a strong router password, and maintain automatic firmware updates. The point to remember is that trustworthy DNS can improve lookup responsiveness, but consistent configuration and measured results matter more than the word “faster”.
