What is DNS, Anyway?
So, you know, at its core, the Domain Name System (DNS) is what lets you use easy-to-remember website names instead of long strings of numbers. Every device connected to the internet has a unique numerical address, called an IP address, like 192.168.1.1. But remembering those numbers for every website would be, well, pretty difficult, right? That's where DNS comes in, acting as the translator.
When you type a web address into your browser, your computer sends a request to a DNS server, which is basically asking, "Hey, what's the IP address for this website?" The DNS server then looks it up and sends the IP address back to your computer. Your computer then uses that IP address to connect to the website's server. This whole process happens in milliseconds, usually, but a slow or unreliable DNS server can make things feel sluggish, you know?
Most internet service providers (ISPs) give you their own DNS servers by default. These are often fine, but they aren't always the fastest or the most private options out there. That's why learning how to change DNS on PC can be such a useful skill, offering you more control over your online experience, actually.
Why You Might Want to Change Your DNS
Changing your DNS server settings on your computer can greatly enhance your internet browsing experience, seriously. There are several good reasons why people choose to switch from their ISP's default DNS, and these reasons often boil down to making your internet feel better, faster, and more secure, you know?
Better Speed
Sometimes, your ISP's DNS servers might not be the quickest ones around, basically. They could be overloaded or just not located very close to you, causing a slight delay every time your computer tries to look up a website's address. By switching to a faster, publicly available DNS server, you can often shave off those tiny delays, making websites load just a little bit quicker. It's not a magic bullet for slow internet, but it can definitely help with the responsiveness of your browsing, you know?
Enhanced Security and Privacy
This is a big one for many people, actually. Some DNS providers offer enhanced security features, like blocking access to known malicious websites or phishing scams. They can act as an extra layer of protection, preventing you from accidentally visiting harmful sites. Also, your ISP can see every website you visit through their DNS servers. Switching to a privacy-focused DNS server can help keep your browsing habits more private, as these services often promise not to log your activity, which is a pretty good thing.
Accessing Blocked Content
In some regions, certain websites or online services might be blocked by your ISP's DNS. This isn't about getting around strict firewalls, but sometimes, changing your DNS server can help you access content that's been restricted at the DNS level. It's a bit like finding an alternate route when the main road is closed, so to speak. This isn't always the case, but it's a possibility for some, you know.
Fixing Connectivity Glitches
Occasionally, issues with your ISP's DNS server can cause network connectivity problems. If you're having trouble connecting to certain websites or experiencing intermittent internet access, changing your DNS can sometimes resolve these issues. It's a simple troubleshooting step that can often fix network hiccups, which is pretty handy to know, actually.
Before You Start: A Quick Check
Before you jump into changing your DNS settings, there are just a couple of things you should do, honestly. These steps will help you stay organized and make sure you can easily revert your changes if you need to, which is always a good idea.
Note Your Current Settings
This is super important, actually. Take note of any DNS addresses you might have set up right now. You can usually find these in your network adapter settings. Write them down in a safe place, like a notepad or a digital document. This way, if you run into any issues with your new DNS servers, or if you just decide you want to go back to your old setup, you'll have all the information you need. It's like having a backup plan, you know?
Choose Your New DNS Server
There are many public DNS servers available, each with its own benefits regarding speed, security, and privacy. You'll want to pick one or two that you'd like to use. We'll talk about some popular options a little later in this guide, but for now, just have a couple of IP addresses in mind. You'll typically need a "preferred DNS" and an "alternate DNS" address, so having both ready is pretty much essential.
How to Change DNS on Your Windows PC
Changing your DNS server on a Windows PC is pretty straightforward, actually, and there are a few different ways you can go about it. Whether you're using Windows 10 or Windows 11, the process is quite similar, and we'll cover the most common methods here. You'll find that it's a simple task that can improve your internet experience, you know.
Method 1: Using Windows Settings
This is arguably the most common and user-friendly way to change your DNS settings, especially with newer Windows versions. It's all done within the modern Settings app, which is pretty convenient.
For Windows 11
On Windows 11, changing the DNS server is very easy. First, you'll want to click the Start button and then select "Settings." You can also just press `Windows + I` on your keyboard, which is a quick shortcut, actually. Once Settings is open, switch to "Network & internet" in the sidebar on the left. Then, click on the network connection you're currently using, like "Wi-Fi" or "Ethernet." Scroll down a bit until you see "DNS server assignment" and click the "Edit" button next to it. Here, you can change the setting from "Automatic (DHCP)" to "Manual" and then input your preferred and alternate DNS addresses. Make sure to save your changes, of course.
For Windows 10
Changing DNS settings on Windows 10 is also pretty straightforward. Start by pressing `Windows + I` on your keyboard to open Settings. In Settings, select "Network & Internet" from the options. On the left sidebar, click on "Status" or "Ethernet" or "Wi-Fi," depending on how you're connected. Then, click on "Change adapter options" or "Change connection properties." Find your active network connection, right-click it, and choose "Properties." Select "Internet Protocol Version 4 (TCP/IPv4)" from the list and click "Properties." Here, you can select "Use the following DNS server addresses" and enter your new preferred and alternate DNS servers. Just remember to click "OK" to save everything, you know.
Method 2: Through the Control Panel
The Control Panel is a classic Windows tool, and it still works perfectly for changing DNS settings, even on Windows 11. This method gives you a similar path to what you might remember from older Windows versions, which some people prefer, actually.
To use this way, first, open the Control Panel. You can do this by searching for "Control Panel" in the Start menu. Once it's open, click on "Network and Internet," and then "Network and Sharing Center." On the left side, you'll see "Change adapter settings." Click on that, and a new window will pop up showing all your network adapters. Find the one you're currently using (it usually won't have a red X on it), right-click it, and select "Properties." From there, the steps are pretty much the same as for Windows 10 Method 1: select "Internet Protocol Version 4 (TCP/IPv4)," click "Properties," and then enter your preferred and alternate DNS server addresses. Don't forget to click "OK" a few times to close all the windows and save your settings, you know.
Method 3: A Quick Command Prompt Trick
For those who like to use command lines, or if you just want another way to change DNS, the Command Prompt can get the job done. This method is a bit more advanced, but it's very effective, seriously. It's a good trick to have up your sleeve, actually.
First, you need to open Command Prompt as an administrator. Search for "cmd" in the Start menu, right-click on "Command Prompt," and select "Run as administrator." Once the black window appears, you'll need to know the exact name of your network adapter. You can find this by typing `ipconfig /all` and looking for the "Description" under your active connection. Then, you'd use commands like `netsh interface ip set dns "Your Adapter Name" static 8.8.8.8 primary` to set the primary DNS, and then `netsh interface ip add dns "Your Adapter Name" 8.8.4.4 index=2` for the secondary. Replace "Your Adapter Name" with the actual name and 8.8.8.8/8.8.4.4 with your chosen DNS servers. This method is powerful but requires a bit more care, you know.
Changing DNS on a Mac
While this guide focuses mostly on Windows PCs, it's worth a quick mention that changing DNS on a Mac computer is also quite possible and offers similar benefits. The process is a bit different, of course, but it's still pretty user-friendly, honestly. You'd typically go into System Settings (or System Preferences on older macOS versions), then to Network, select your active connection, click "Details" or "Advanced," and then find the DNS tab to add your new server addresses. So, no matter your computer, you can usually take control of your DNS, which is a good thing.
What About Router DNS?
It's also worth noting that you can often change the DNS settings directly on your home router, too. When you change DNS on your router, every device connected to that router (your PC, phone, smart TV, etc.) will then use those new DNS settings. This can be a really convenient way to apply DNS changes across all your devices without having to set each one individually, you know?
However, changing router DNS settings is a bit more involved and varies a lot depending on your router's brand and model. You usually need to log into your router's admin interface through a web browser. If you're comfortable with that, it's a powerful option, but for changing DNS on PC specifically, the methods above are what you're looking for, actually. We cover windows, mac, and router DNS changes, plus troubleshooting tips & more in other places, so there's plenty of information out there.
Common DNS Servers to Consider
When you decide to change DNS on PC, you'll need some new addresses to plug in. There are several popular public DNS providers, each with its own advantages. Here are a few that many people use, basically:
Google Public DNS
Google Public DNS is one of the most widely used alternative DNS services. It's known for being fast and reliable. To use Google Public DNS, you'll need to explicitly change the DNS settings in your operating system or device to use their IP addresses. The addresses are straightforward: 8.8.8.8 for the preferred DNS and 8.8.4.4 for the alternate DNS. Many people find it improves their browsing speed, you know.
OpenDNS
OpenDNS offers both speed and security features, including filtering out phishing sites and offering parental controls if you sign up for their services.

It's a great choice if you're looking for an extra layer of protection while you browse, which is pretty useful, actually.
Cloudflare DNS
Cloudflare's 1.1.1.1 is another excellent option, heavily focused on speed and privacy. They claim to be the fastest public DNS resolver, and they are committed to not logging your IP address or selling your data. Their addresses are 1.1.1.1 (preferred) and 1.0.0.1 (alternate). It's a strong contender if you prioritize both quick loading times and keeping your online activity private. Learn more about Cloudflare's 1.1.1.1 DNS here.
Troubleshooting Tips
Sometimes, after you change DNS on PC, things might not work perfectly right away. Don't worry, that's totally normal, actually. Here are a few common issues and what you can do about them:
- No Internet Access: If you lose internet connection after changing DNS, the first thing to do is double-check the DNS addresses you entered. Make sure there are no typos. If they look correct, try reverting to your old DNS settings (which you hopefully wrote down!). Then, try restarting your computer and your router.
- Slow Internet: If your internet feels even slower, the new DNS server might not be ideal for your location. Try switching to a different public DNS server from the list above. Sometimes, what's fast for one person isn't the fastest for another, you know.
- Website Not Loading: If only specific websites aren't loading, try clearing your browser's cache and your computer's DNS cache. To clear the DNS cache on Windows, open Command Prompt as administrator and type `ipconfig /flushdns` and press Enter.
- Forgetting Old Settings: If you didn't write down your old DNS settings, you can usually set your adapter back to "Obtain DNS server address automatically." This will make your computer use your ISP's default DNS again, which should get you back online, basically.
