Open your router admin page, find the WAN or Internet DNS setting, and enter 1.1.1.1 as primary and 1.0.0.1 as secondary. Save, reboot the router, then restart your IPTV player.
This change applies to every device in your home at once. It is a simple way to give your streams a cleaner DNS path.
Quick Answer: What You Need to Change
DNS stands for Domain Name System. It works like a phone book for the internet. It turns a name such as a website address into the number your device needs to connect.
By default, your router uses the DNS servers of your internet provider. Cloudflare offers public DNS servers that anyone can use. You swap the provider's numbers for Cloudflare's numbers. That is the whole job.
| Setting | Value to enter | Notes |
|---|---|---|
| Primary DNS (IPv4) | 1.1.1.1 | Main Cloudflare address |
| Secondary DNS (IPv4) | 1.0.0.1 | Backup address |
| Primary DNS (IPv6) | 2606:4700:4700::1111 | Only if your router supports IPv6 |
| Secondary DNS (IPv6) | 2606:4700:4700::1001 | Only if your router supports IPv6 |
| Player buffer / cache | 5,000 ms | Set inside your IPTV player |
Most homes only need the two IPv4 lines. Leave the IPv6 lines empty if you do not see them in your router.
Why Change DNS for IPTV at All?
An IPTV app asks for DNS lookups every time it loads a playlist, a guide or a stream. If the lookup is slow, the app waits. If the lookup fails, you may see a spinning wheel or an error.
Here are the common reasons people switch:
- Slow lookups: Some provider DNS servers answer slowly at busy hours.
- Failed lookups: A weak provider server can time out and make an app look broken.
- Provider handling of traffic: Some internet providers manage certain traffic differently. A different DNS path is one of the first things people try to reduce this effect.
- One setting for all devices: Change it once on the router and every TV, box and phone follows.
Be realistic about what DNS can do. It changes how names are looked up. It does not make your internet line faster. If your connection is weak, DNS alone will not fix it. It is one tool in a small kit, along with a good player buffer and a stable network.
What Is Cloudflare 1.1.1.1?
Cloudflare 1.1.1.1 is a public DNS resolver run by Cloudflare, a large internet infrastructure company. A resolver is the server that answers your DNS questions.
The address 1.1.1.1 is short and easy to remember. That is why many guides use it. The second address, 1.0.0.1, is a backup. If the first one does not answer, your router tries the second.
For background on how streaming over the internet works, you can read the Wikipedia OTT page. OTT means "over the top", which is video sent over the open internet instead of a cable box.
Before You Start: A Short Checklist
Take two minutes to prepare. It saves trouble later.
- Find your router's admin address. It is often printed on a sticker under the router. Common forms look like 192.168.0.1 or 192.168.1.1.
- Find the admin username and password. They are often on the same sticker, unless you changed them.
- Write down your current DNS values. If something goes wrong, you can put them back.
- Connect your computer or phone to the router's Wi-Fi, or use a network cable.
Router menus differ by brand. The names below are the usual ones, but yours may use slightly different words. Look for sections named Internet, WAN, Network or DHCP.
How to Configure Cloudflare DNS on Your Router
Follow these steps in order. Each one is short.
- Open a browser and type your router's admin address in the address bar.
- Log in with the admin username and password.
- Open the Internet, WAN or Network settings page.
- Look for a field named DNS, DNS server or Primary DNS. If you see "Automatic" or "Obtain DNS automatically", switch it to manual.
- Enter 1.1.1.1 in the primary field.
- Enter 1.0.0.1 in the secondary field.
- Click Save or Apply.
- Restart the router if it does not do so by itself.
After the router is back online, turn your streaming device off and on again. This makes the device ask the router for fresh network settings.
If your router has a separate DHCP DNS setting
Some routers have two places for DNS. One is for the router's own connection (WAN). The other is the DNS that the router hands out to your devices (LAN or DHCP).
If you see both, set Cloudflare in both places. Then every device in your home receives the same addresses.
If your router does not allow DNS changes
Some routers supplied by internet providers lock this field. You have three safe options:
- Ask your provider whether the DNS field can be unlocked.
- Set the DNS on each device instead. Android TV boxes, Fire TV and Apple TV allow it in their Wi-Fi or network settings.
- Add your own router behind the provider's box and set DNS on your own router.
Router Brands: What to Look For
Every maker names things a little differently. This table shows where the DNS field usually hides.
| Router type | Where to look |
|---|---|
| Provider-supplied box | Internet or WAN page. May be locked. |
| Home Wi-Fi router (consumer) | Internet, WAN or Network, then DNS |
| Mesh Wi-Fi system | Usually inside the maker's phone app under Internet or Network |
| Open firmware routers | Network, Interfaces, then Advanced settings for DNS |
If you cannot find the field, search the router's model name with the words "change DNS". The maker's support page will show the exact menu.
Check That the New DNS Works
Do not guess. Check it. Here are simple ways:
- Open your router's status page. The DNS values should now show 1.1.1.1 and 1.0.0.1.
- On a computer, open a terminal or command prompt and type nslookup example.com. The line named "Server" should show 1.1.1.1 or the router address.
- Open your IPTV player and load a stream. It should start without a long delay.
If the router acts as a DNS relay, the computer may show the router's own address. That is normal. The router then passes the question on to Cloudflare.
Pair DNS With the Right Player Settings
DNS helps with lookups. Your player helps with smooth playback. Both matter.
A buffer is a small store of video that the player loads before it plays. A bigger buffer gives the app more room when the network wobbles. A buffer or cache value of 5,000 ms (five seconds) is a good starting point for IPTV on a home network.
These players are commonly used with SubTV IP:
- TiviMate 5.x
- IBO Player Pro
- IPTV Smarters Pro
- Kodi 21
- Flex IPTV
The exact name and place of the buffer option changes from app to app. Open your player's settings and look for words like Buffer, Cache or Network. If you cannot find it, check the app's help page.
Devices that work well
The same router change helps all of these devices:
- Fire TV Stick 4K Max
- Samsung Smart TV (Tizen)
- LG webOS
- Android TV Box
- Xiaomi Mi Box S
- Apple TV
Because you changed the router, you do not need to repeat the work on each one. That is the main benefit of this method.
Build a Stable Home Network for 4K
SubTV IP offers 4K streams at 60 fps in HEVC, plus a server cluster built to avoid stalls and 99.9% uptime. Your home network still has to carry the stream to the TV. Small habits make a big difference:
- Use a network cable when you can. Wired links are steadier than Wi-Fi.
- Keep the streaming box near the router. Walls and distance weaken Wi-Fi.
- Use the 5 GHz Wi-Fi band for TVs close to the router. It is usually faster over short range.
- Limit big downloads while you watch. Game updates and cloud backups can fill the line.
- Restart the router now and then. It clears small memory problems.

How to Set Cloudflare DNS on a Single Device
If your router is locked, set DNS on the streaming device itself. The path differs by device, so the steps below are general. Look for the same words in your own menu.
- Open the device settings and go to Network or Wi-Fi.
- Select your home network and open its advanced or IP settings.
- Change the IP setting from automatic (DHCP) to manual or static. Some devices keep DHCP and show a separate DNS field.
- Keep the IP address, gateway and subnet values exactly as they were. Only change the DNS fields.
- Type 1.1.1.1 in DNS 1 and 1.0.0.1 in DNS 2.
- Save, then reconnect to the network and open your IPTV player.
Be careful with manual IP settings. If you type a wrong gateway, the device loses its connection. If that happens, switch the setting back to automatic and start again.
DNS, Buffer and Bandwidth: What Each One Does
People often mix these three ideas. Each one fixes a different problem, so it helps to know the difference.
| Item | What it controls | Symptom when it is wrong |
|---|---|---|
| DNS | How fast names turn into addresses | Long wait before a stream or playlist loads, or load errors |
| Buffer / cache | How much video the player stores ahead | Short pauses during playback when the network wobbles |
| Bandwidth | How much data your line can carry | Lower picture quality or constant stalls, especially in 4K |
| Wi-Fi signal | How well data reaches the device | Random drops, worse in rooms far from the router |
Start with the cheapest fixes. Change DNS, set the buffer, and move to a cable if you can. Only then think about changing your internet plan.
A Simple Routine for Steady Streaming
Once the setup is done, keep it healthy with a short routine:
- Write down your router settings after any change, so you can restore them.
- Restart the router and the streaming box every few weeks.
- Keep your player app and your device software up to date.
- Change the router admin password from the default to a strong one.
- If a problem appears after a router update, check that the DNS values are still saved. Some updates reset them.
These small habits take little time and prevent most of the problems people blame on DNS.
Common Problems and Fixes
Cause: The router still uses old DNS values -> Fix: Save and reboot
Some routers keep the old values until they restart. Save your change, power the router off for 30 seconds, then power it on. Check the status page again.
Cause: A device has its own manual DNS -> Fix: Set it back to automatic
If a TV or box has a fixed DNS entered by hand, it ignores your router. Open that device's network settings and switch DNS to automatic. It will then follow the router.
Cause: Wrong numbers typed -> Fix: Re-enter them carefully
A single wrong digit breaks lookups and nothing loads. Re-type 1.1.1.1 and 1.0.0.1. Do not add spaces or extra dots.
Cause: The provider router is locked -> Fix: Use device-level DNS
When the router will not accept changes, set Cloudflare on each streaming device instead. It takes longer, but it gives the same effect for that device.
Cause: Stream still buffers -> Fix: Check the line and the buffer
DNS is not a speed boost. If playback still stalls, check your Wi-Fi signal, try a cable and set the player buffer to 5,000 ms. If a problem remains, contact support over WhatsApp.
Is Changing DNS Safe?
Yes. It is a normal setting, and you can undo it any time. Write down your old values first. If you want to go back, enter them again or set the field to automatic.
One thing to know: DNS only handles lookups. It does not hide your activity from your internet provider by itself. Do not treat it as a privacy tool on its own.
