How to Change DNS on Your Router (And Why It Upgrades Your Whole Network)
Every time you type a website address, your device quietly asks a DNS server, “Hey, what’s the actual numeric address for this name?” That little lookup happens before anything loads. By default, your router uses whatever DNS server your internet provider assigns — and that’s often not the fastest, most reliable, or most private option available.
The good news: you can change it. And if you make that change on your router rather than on each individual gadget, you upgrade your entire network in one move. This guide walks you through why you’d want to change DNS, which public DNS servers are worth considering, and exactly how to swap them on your router — in plain English.
Key Takeaways
• Changing DNS on your router applies the new DNS server to every device on your network automatically — phones, laptops, TVs, consoles, and IoT gadgets.
• Switching from your ISP’s default DNS can mean faster lookups, better reliability, optional security filtering, and more privacy.
• Popular public DNS servers include Google (8.8.8.8), Cloudflare (1.1.1.1), Quad9 (9.9.9.9), and OpenDNS.
• The general process: log into your router admin page, find the DNS or WAN settings, enter a primary and secondary DNS, save, and reboot.
• If anything breaks, reverting is as simple as switching the setting back to “automatic” or “obtain from ISP.”
Why Would You Change Your Router’s DNS?
The DNS server your ISP hands you works — but “works” isn’t the same as “best.” Here are the real reasons people switch.
Speed. Some public DNS resolvers respond to lookups faster than a congested ISP resolver, which can shave milliseconds off the moment a page starts loading. It won’t make your internet plan faster, but it can make browsing *feel* snappier.
Reliability. ISP DNS servers occasionally go down or get overloaded, which can make it seem like “the internet is broken” even when your connection is fine. Established public resolvers are built for uptime and tend to be more dependable.
Security and filtering. Certain DNS providers block known malicious domains at the lookup stage — so a phishing or malware site simply never resolves. Others offer family-friendly filtering that blocks adult content network-wide.
Privacy. Some ISPs log the domains you look up. Privacy-focused public resolvers commit to not selling that data and often support encrypted DNS, keeping your browsing habits more to yourself.
Bypassing ISP DNS quirks. If your provider redirects mistyped addresses to ad-filled “search” pages, or if a site loads for everyone but you, switching DNS often clears it up. If you’re troubleshooting that kind of problem, it helps to understand the difference between a .
What Does Changing DNS on the Router Actually Do?
Here’s the part most guides gloss over. You can change DNS in two places:
- Per device — you set the DNS on your laptop, then again on your phone, then again on the tablet. Each change only affects that one gadget.
- On the router — you set it once, in one place, and it cascades to everything connected.
When your router hands out network settings to devices (via DHCP), it tells each one which DNS server to use. Change the router’s DNS, and every device that joins your network — now and in the future — automatically picks up the new resolver. No per-device fiddling required.
This distinction is the difference between fixing one squeaky door and replacing the front gate of the whole building. To dig deeper into how this fits into the bigger picture, see Networking & DNS for Hosting: The Complete Guide to How Visitors Reach Your Server.
Changing your DNS server on the router (rather than on each device) is the high-leverage move most people miss. Set it once on the router and *every* device on your network instantly uses the better DNS: phones, laptops, smart TVs, game consoles, and IoT gadgets — including the ones you can’t easily configure individually. A smart bulb or a streaming stick has no DNS menu of its own, but it still obeys the router. So when you want faster, more reliable, or security-filtered DNS for your home or office, change it at the router and you’ve upgraded the entire network in a single step — including the devices that have no DNS setting at all.
Which Are the Best DNS Servers to Use?
You’ll enter two addresses on your router: a primary and a secondary (the backup, used if the primary doesn’t answer). It’s fine to mix providers, but most people pick one provider’s pair for consistency. Here are the most popular public options and what each is good for.
| DNS provider | Primary | Secondary | Best for |
|---|---|---|---|
| Google Public DNS | 8.8.8.8 | 8.8.4.4 | Speed and broad reliability |
| Cloudflare | 1.1.1.1 | 1.0.0.1 | Privacy and fast lookups |
| Quad9 | 9.9.9.9 | 149.112.112.112 | Security filtering (blocks malicious domains) |
| OpenDNS | 208.67.222.222 | 208.67.220.220 | Content filtering and parental controls |
A quick way to think about it:
| If you want… | Consider |
|---|---|
| The simplest “just make it reliable” choice | Google (8.8.8.8 / 8.8.4.4) |
| Privacy plus speed | Cloudflare (1.1.1.1 / 1.0.0.1) |
| Built-in protection from malicious sites | Quad9 (9.9.9.9) |
| Blocking adult or specific content network-wide | OpenDNS |
There’s no single “correct” pick — it depends on whether you’re optimizing for speed, security, or filtering. If you’re curious about the broader concept first, here’s a primer on .
How Do You Change DNS on Your Router? (Step by Step)
Every router brand has a slightly different menu, so treat this as the general roadmap rather than exact button names. Check your router’s label or manual if a step looks different.
- Find your router’s address. It’s usually printed on a sticker on the router. Common ones are `192.168.1.1`, `192.168.0.1`, or `10.0.0.1`.
- Log into the admin page. Type that address into a web browser. Enter the admin username and password (also often on the sticker — change these later if they’re still the default).
- Locate the DNS settings. Look under sections named Internet, WAN, Network, DHCP, or Advanced. The DNS fields are frequently tucked inside WAN or DHCP settings.
- Switch from automatic to manual. There’s usually a toggle like “Obtain DNS automatically” versus “Use these DNS servers.” Choose the manual option.
- Enter your chosen DNS. Type the primary address in the first field and the secondary in the second. For example, `1.1.1.1` and `1.0.0.1` for Cloudflare.
- Save and apply. Click Save, Apply, or OK. The router may warn that the network will briefly drop — that’s normal.
- Reboot if prompted. Some routers need a quick restart for the change to take effect. Wait a minute for it to come back online.
That’s it. Once the router is back up, every device that reconnects will be using your new DNS.
Should You Change DNS Per Device or on the Router?
Both have a place:
- Router-wide is the right default for most homes and offices. One change, whole network covered, including devices with no DNS menu.
- Per device makes sense when you only want *one* gadget on a different DNS — say, a work laptop that needs a specific resolver — while leaving the rest of the network alone.
If you’re managing a shared home network and want consistent speed, security, or filtering everywhere, the router is almost always the smarter place to set it.
How Do You Verify the Change Worked?
After saving, confirm your devices are actually using the new DNS:
- Reconnect a device. Toggle Wi-Fi off and on (or unplug and replug Ethernet) so it pulls fresh settings from the router.
- Check the assigned DNS. On a computer, open your network status or run a quick `ipconfig /all` (Windows) or look in network settings (Mac) and confirm the DNS server listed matches what you entered.
- Browse normally. Load a few sites. If pages open fine, you’re set.
If a site that worked before now misbehaves, or names won’t resolve at all, your cache may be holding old data — clearing it usually fixes lingering hiccups. Here’s how to .
What If Something Goes Wrong After Changing DNS?
Reverting is painless, which is why experimenting is low-risk:
- Log back into the router admin page.
- Return to the same DNS settings.
- Switch back to “Obtain DNS automatically” or re-enter your ISP’s DNS, then save and reboot.
If only certain sites fail to load after the switch, the resolver isn’t necessarily the culprit — sometimes it’s a stale cache or a server-side issue. If you keep seeing a “server not responding” message specifically, that’s worth troubleshooting on its own.

Frequently Asked Questions
Does changing DNS on my router make my internet faster? It can make lookups quicker, which makes browsing feel more responsive, but it doesn’t increase your actual bandwidth. If your plan is 100 Mbps, it stays 100 Mbps — DNS just affects how fast names get resolved into addresses.
Will changing my router’s DNS affect every device? Yes — that’s the main benefit. Every device that gets its settings from the router automatically uses the new DNS, including phones, smart TVs, consoles, and IoT gadgets that have no DNS menu of their own.
Is it safe to use a public DNS server like 1.1.1.1 or 8.8.8.8? Reputable public resolvers from established providers are widely used and safe for everyday browsing. Some even add security filtering that blocks malicious sites. Just stick to well-known providers rather than random addresses you find online.
How do I undo the change if it causes problems? Log back into your router, return to the DNS settings, and switch back to “obtain DNS automatically” (or re-enter your ISP’s servers). Save and reboot, and you’re back to the original setup.
Do I need to change DNS on both my router and my devices? No. If you set it on the router, individual devices don’t need separate changes — they’ll inherit the router’s DNS. Per-device changes are only for when you want one specific gadget to use a different resolver.
