The internet is one of the essential features of our everyday lives. It has become a necessary part of how we communicate, how we work, how we shop, and how we learn. But have you ever thought about how your router's DNS could affect all these things?
What are the advantages of changing the router DNS server to our networks? What are some disadvantages that come with this procedure? These questions will be answered in this post.
How Does DNS Server Work?
The router DNS is one of the most critical aspects of your router. Unfortunately, it's also one of the easiest to change without knowing what you are doing! A DNS server enables your computer to translate an IP Address into a domain name (i.e., google.com).
It matches the hostname to one or more IP addresses and returns the most relevant result to you when queried with the corresponding URL in question. Domain Name System handles translating friendly domains into numeric IP addresses. Your home network can usually rely upon the DNS servers of your IP provider.
Whenever the browser sends the server domain names, the server must undergo a moderately complex interaction with other servers to return an IP address. If this is a valid domain name, the DNS server can cache that information for fast and accurate access. Now that interaction is down to numbers, the machine displays the pages you want to view.
Reasons Why You Need to Change DNS
When you have an ISP-provided network's DNS server running slow or cannot be adequately cached, this can slow or disrupt your connections. Switching to DNS servers for faster performance can speed up your web surfing.
Some DNS service providers also use business-savvy add-ons. The system helps parents manage children's access to unapproved information on the internet without limits. Your ISP knows where you can visit the internet or is likely unaware.
However, some ISPs have discovered a better way of monetizing DNS traffic. You are automatically diverted to a search and advertising site when you hit an incorrect URL with no actual IP address.
DNS under Attack
Have you experienced receiving an email from your bank, but it seems suspicious? Some of the website owners use fraudulent web design which looks exactly like PayPal or bank. They propagate links using emails, fraudulent advertisements, or other forms of marketing. The only feature which hides these fraudulent transactions is the address bar.
How to Change Your Router's DNS
If you want to change the DNS server for your entire home network, you must do so through your router. By default, your router connects to the DNS servers of your internet service provider. If you update the DNS server on your router, it will be used by all other devices on your network.
- To begin, you need to access your router's web interface. Please note the steps may vary depending on your router. If you are not sure, you may check your router manuals to ensure your router's specific model. From its manual, you can see the details you need, such as the username and password of the router only if you didn't change it before.
- From the web interface, you will see the DNS server option. Change it, and the setting will apply to your entire network. The option may be under LAN or DHCP server settings since the DNS server is given to devices connected to your network through the DHCP protocol.
How to Change DNS Server in a Specific Router
Changing the DNS server is not as challenging as you think, but like what we mentioned earlier, those steps might vary depending on your router's manufacturer. If your router is one of the most popular, then these steps may help you.

Step 6: Click the save option to save changes.
Benefits of Changing Your Router's DNS
There are several reasons why changing the DNS server is essential:
- A better DNS server can make your network faster and more sure.
- It can provide better security on your network.
- Faster servers than the ISP server, allowing requests to be handled more quickly and smoothly.
- Geographically nearby servers provide for a more direct connection and, as a result, quicker speeds.
- Parental control options, such as OpenDNS.
- Some alternative DNS servers provide anti-phishing protection.
Best DNS Server to Improve Network Safety
Here are the five best DNS servers you can use to improve your network security and filter malware sites to avoid DNS attacks.
- Google Public DNS with the IP Addresses 188.8.131.52 and 184.108.40.206
- OpenDNS with the IP Addresses 220.127.116.11 and 18.104.22.168
- DNSWatch with the IP Addresses: 22.214.171.124 and 126.96.36.199
- OpenNIC with the IP Addresses: 188.8.131.52 and 184.108.40.206
Which is the Best DNS Server
For nearly 10 years, Google’s public DNS network contained simple to remember addresses (8.8.1 and 8.5.4). Google said it would use secure connections and hardened against cyber threats as its website was expected. OpenDNS offers secure DNS for longer, but it also provides many other solutions for the domain name.
