How to Change DNS Settings on Your OS or Router

DNS server settings sounds like something computer science majors and elite hackers talk about at the coffee shop. Despite its foreboding name, however, the technology is one of the common supporting backbones of the internet. If you’ve ever typed a URL into your browser’s address bar and successfully visited a website, you put a DNS server to work.

Changing DNS settings on your home router or computer can alter the way you interact with the web. Not only can a simple tweak make parts of the internet a bit faster, it can also help you circumvent blocked and censored websites, access content restricted in your country, filter malicious websites, and even protect your children online.

What is DNS?

The internet works by sending information back and forth between computers. A device makes a request, a server relays that request to the appropriate destination, those servers pass it back, and a website loads on your screen. All of this happens thanks to internet protocol addresses, or simply IP addresses. Each device connected to the internet is assigned a unique series of numbers used to identify them on the world wide web. Think of it like a mailing address. If you want to send a package to someone, write their address on a box and the postal service will deliver it.

IP addresses aren’t very friendly to human eyes. Looking at something like doesn’t make much sense, and you can forget about memorizing dozens of those to perform your daily internet tasks. That’s where DNS comes into play. DNS stands for Domain Name Service, or sometimes Domain Name Servers, and it works like a human readable label for those seemingly random IP addresses. Instead of typing in all the numbers each time you want to visit a website, you enter Facebook.com, a DNS server looks up the IP address associated with that URL, and you get redirected.

The nature of DNS servers places them between your computer and the rest of the internet. Before you can access a website, a DNS server has to do its job. This gives DNS services a unique opportunity to filter, block, and unblock content before it even reaches your home. If a website is flagged as malicious or inappropriate, the DNS server can deny access without you even knowing it happened.

DNS and Your Home Connection

The entire process of typing in a URL and having a DNS server match it to an IP address takes place in fractions of a second. Most people don’t think about where it takes place, either. When you sign up for internet service with your local ISP, you gain access to their DNS servers. Part of the set-up process when a technician installs a modem or router at your home is to make sure the DNS settings are configured to the local provider’s servers. Without them, you can’t do very much online.

What most people don’t realize is that you’re under no obligation to use your ISP’s DNS servers. In fact, in many cases there’s a great advantage in not doing so. To make the change all you need is access to a third party DNS provider, which in many cases is either free or extremely low cost, and a few minutes of spare time. That’s it. And best of all, it doesn’t take a tech genius to change DNS server settings.

How to Change Your DNS Settings

Switching DNS settings isn’t nearly as complicated as you might think. All you have to do is connect to the internet, find the right settings page, enter your new details, and you’re done. The process can take a bit of time depending on your familiarity with your operating system and internet hardware, however.

There are two main ways you can change DNS settings. The first is through your router, which will affect every device that connects to your network, including Wi-Fi. The second is by changing settings on a particular device. This only affects that computer or smartphone, which is perfect for filtering content on tablets or laptops kids frequently use.

Change DNS Settings on a VPN

When you use a virtual private network you also use their DNS servers. This is done to prevent local DNS leaks that may divulge your real IP address and location. You can still use third party DNS servers if you’re on a VPN, however. Not all providers will allow it, and the process will vary from software to software, so it might take a little experimentation before you can find the correct option.

How to change DNS settings on a VPN:

  1. Open your VPN software.
  2. Find the settings page.
  3. Look for a DNS or nameserver entry.
  4. Enter the new DNS details.

How to Open Your Router’s Admin Page

The first stumbling block for many users looking to change DNS settings is figuring out how to access their router’s admin page. After all, it’s not something you need to do that frequently. The method will vary depending on the brand of your router, but the basic idea remains the same. All you need is physical access to the router, a computer that’s plugged into it, and a web browser.

If you aren’t sure what brand your router is, look on the bottom of the device. Most companies place stickers here that display the make and model number along with the default username, password, and access address. If this is the case you have all the information you need to reach the admin page. Simply open up your browser, type in the default IP address, and you’re ready to go.

How to open your router’s admin page:

  1. Connect your computer to the router (on WiFi or ideally, with a cable.
  2. Open a browser window.
  3. In the URL bar type in the router’s IP address*. This will usually be something like or
  4. Log in using your username and password.

* Finding your router’s address is usually easy: Fire up the Properties for the connection (i.e. on WiFi click on the network name and see the Properties button) you’re on and check the DNS server. Unless there are some custom settings on your router, the IP address should look something like the above.

Once you have access to the router’s settings page, look for a settings tab related to internet connections. Some routers hide the DNS server configuration options under an advanced section to make sure no one accidentally changes it. If you can’t locate the tab by trial and error, check the router’s documentation for detailed information.

Advantages of Using a Third Party DNS Service

Just about everyone on the internet uses their local ISPs DNS service without even thinking about it. You can connect to the internet just fine, so why bother messing with it? There are a number of advantages using a third party DNS service can bring, however, including speed, security, and access to brand new content.

Some of the immediate advantages of using a third party DNS service include:

Bypass censored and blocked websites – Blocking content at the DNS level is a common tactic used by corporations and governments to prevent people from viewing certain content. If you live in a country that doesn’t allow Facebook, for example, your ISP may simply filter it from their DNS servers to prevent access. If you use a third party DNS service, however, you can bypass these blocks with almost no effort.

Stop phishing attempts – Phishing scams are attempts at getting sensitive user information such as e-mail addresses or passwords by disguising a link with a more trustworthy URL. It may look and act like your bank’s website, but in reality it’s harvesting your information to use for nefarious purposes. If you’re not paying close attention, it can be easy to fall victim to this kind of traps. Several third party DNS services offer built-in protection that block most phishing websites by default.

Improved speed – ISPs aren’t under any pressure to provide faster name look-ups. Depending on your location and the location of the DNS service you want to use, you might see a noticeable increase in speed when you change servers. Seeing a 50-60% increase in URL resolution isn’t all that uncommon.

Filter the web – An extremely convenient way to block websites from your entire home connection is to add filters to your DNS server. It’s perfect for increasing productivity by blocking distracting social media websites or for keeping kids safe from harmful online content. ISP operated DNS servers usually don’t allow filtering, but third party services such as OpenDNS do.

Which DNS Services to Use

DNS services come in two basic varieties: free and paid. Free DNS services offer basic servers with a variety of no-cost features, including phishing protection and faster look-ups. Paid services add extra features such as configurable web filters to help make your surfing safer. Which option you choose is up to you and your needs, but both can deliver faster speeds depending on location.

Just like free proxies and free VPNs, there can be some risk associated with using lesser-known no-cost providers, including privacy violations, activity logging, and censored websites. For this reason, it’s best to do a little research on your DNS provider before changing settings. There are a few free and low-cost DNS services that focus on open availability and ease of use, however, some of which are provided by big name companies.

Some of our favorite, reliable services that offer free or paid DNS servers:

OpenNIC Project – An alternative DNS provider that prides itself on being open and democratic. Delivers DNS servers that are completely free, promote neutrality, and stop DNS hijacking. Privacy advocates consistently list OpenNIC as their favorite DNS service.

OpenDNS – One of the more popular alternative DNS providers, and for good reason. The OpenDNS mission statement is to provide safety, reliability, and efficiency for the entire internet. It does this by filtering dangerous websites and building its entire network around speed. It even features both free and paid VIP services for homes, families, and businesses, all of which are surprisingly cost effective.

Google Public DNS – Another extremely popular alternative DNS service, Google delivers better security, better speeds, and more accurate DNS look-ups than many local service providers. It’s also completely free.

Norton ConnectSafe – A paid DNS service operated by the anti-virus and digital security giant Norton. Offers several different plans geared towards safety and security, with several options for web filtering that may be useful to parents.

Can Changing DNS Servers Replace a VPN?

While DNS servers can bypass blocked websites, allow access to foreign video streaming services, and even protect your privacy, they’re not a true substitute for a good virtual private network.

VPNs encrypt the data you send through the web, which is a fundamental requirement for online privacy. This helps mask the information you send across the internet to prevent digital surveillance attempts, ISP tracking efforts, and data snoopers. Encryption makes it safer to do your usual online tasks, whereas DNS servers simply fetch websites. A VPN will also let you change virtual locations for better access to Netflix, Hulu, YouTube, and BBC iPlayer videos from other countries.

It’s possible to use a third party DNS service along with your VPN, however, which delivers the benefits of speed, security, location variability, and privacy offered by both. All you need to do is change the DNS options in your VPN software. See the instructions above for a more detailed guide.
