The quick answer
Router DNS is useful when you want compatible home devices to share a Residential US IP streaming connection. Devices must use that router’s DNS settings. USip routes supported service traffic selectively; your ISP’s public address stays in place, and other apps or websites may use their usual route. Smart DNS does not provide VPN encryption.
Start with the next step for your home
- New to USip? Choose your streaming service and Residential US IP offer. Confirm Smart DNS access for your chosen plan with USip Support before subscribing for router use.
- Already have Smart DNS access? Register your home connection, then follow the current router setup instructions using the service credentials from your welcome email.
- Already configured, but something is not working? Choose the next check for the affected device or streaming service.
Your home streaming connection
Choose a Residential US IP for your router.
Select your streaming service to see its USip offer. For a router or TV, confirm Smart DNS access for your chosen plan with USip Support before subscribing. Your service credentials and setup instructions arrive by email; use them with the current Smart DNS guide.
1. Configure the router once for your home devices
The main benefit is fewer individual settings to maintain. Your living-room TV, bedroom streaming box and other compatible devices can use the same DNS configuration when they connect through your router and accept its network settings. That can be especially useful for a player with limited DNS controls of its own.
Choose router setup when you manage the home network and want the configuration available across it. Choose individual-device setup when you want to configure just one TV or cannot change the router. Wi-Fi and Ethernet devices can both benefit; what matters is which network supplies their DNS settings.
Start with the streaming service you actually want to watch. Each device still needs access to its app and the appropriate streaming account. The number of devices connected to a router is separate from a streaming subscription’s simultaneous-playback limit.
2. Check where your router controls DNS
Have your router model, administrator access and current settings ready. Save a screenshot of the DNS configuration before changing it. Use the administration address and login for your own router, following its manual; there is no universal address or password for every home.
Router menus often separate WAN or Internet DNS, used upstream by the router, from LAN or DHCP DNS, supplied to connected devices. Which setting you need depends on the model and how devices obtain DNS. ASUS documents these as distinct controls in its WAN settings and DHCP settings.
Follow the router section of the current USip DNS instructions alongside your manufacturer’s model-specific guide. If your internet provider has locked the DNS fields, ask USip Support about your setup before choosing a plan.
3. Register the home connection after subscribing
With Smart DNS access confirmed, use the service credentials from your “Your Account is Ready” email. Open Register your home connection on a computer or phone connected to the same home network as your streaming devices. Turn off its VPN; on a phone, use home Wi-Fi and turn off mobile data.
Follow the guide into the setup wizard and register the connection with your USip service username and password. Registration identifies the home network automatically; you do not need to type its public IP. These credentials are separate from your router administrator login and streaming-app account.
4. Save the DNS settings and let devices reconnect
Use the current primary DNS and secondary-field instructions in Add the USip DNS address. Apply them to the appropriate router DNS fields and save. Public DNS examples in a manufacturer’s article are not substitutes for the USip settings.
Allow up to 15 minutes before testing playback. Save without restarting the router where possible. If your model requires a restart and your public IP changes, register your home connection again.
Reconnect a streaming device to the network if it is still using its previous DNS settings. Start by testing one device before moving through the others. That makes it easier to confirm the shared configuration is working.
5. Check devices that use their own network settings
A device with manually entered DNS, private or encrypted DNS, or an active VPN may use a different path. ASUS specifically notes that clients can switch to DNS over HTTPS and bypass the preferred router DNS in its WAN DNS guidance. Check these settings if one device behaves differently from the others.
For a guest network, mesh system or second router, confirm which unit supplies DNS to the device. Sharing a home does not necessarily mean sharing the same DNS configuration. Keep devices on the intended home connection during registration and testing, and ask support about a setup you cannot identify.
6. Test each streaming app and keep registration current
Open your chosen app on the first TV or streaming player and test the programme or live channel you intend to watch. Then check the other devices you plan to use. A general IP-checking website may still show your normal ISP address because this DNS method handles supported traffic selectively.
Follow USip’s playback check on each device. If a service fails, note its name, the device and the exact error. Our streaming troubleshooting guide helps separate connection, app and account issues.
A router reboot or an ISP change can give your home a new public IP. Repeat home-network registration when that happens. If problems continue, send your router model, playback device and service details to USip Support.
Choose the next check for your result
- No connection set up yet: choose your streaming service and confirm the Smart DNS option for your router.
- It worked until the router restarted: register the home connection again if its public IP changed.
- One device fails but another works: check which DNS and network the affected device uses. Then follow Smart DNS troubleshooting.
- DNS is saved but a service is blocked: open Streaming Doctor with that service, device and error.
- An IP lookup still shows your home country: follow the playback check on the streaming device. This lookup alone does not establish a Smart DNS fault.
Quick questions
Will all devices in my home use the router DNS setup?
Devices connected through that router can share the setup when they use its DNS settings. Devices with their own DNS, a VPN or a different network path need a separate check. This applies to supported service traffic and does not promise unlimited simultaneous streaming.
Do I also need to change DNS on every TV?
Usually you can leave devices receiving network settings automatically when the router supplies the intended DNS. Check the router’s model-specific instructions and verify playback. A device with a manual DNS override may need its own settings adjusted.
Does changing router DNS give every website a US IP?
No. This setup selectively handles supported services. It does not replace your ISP’s public address or provide a full-network VPN tunnel. Test your selected streaming service on the actual device rather than treating a general IP lookup as the sole result.
