If you want to completely change a DNS server for your home network, you will need to do this on your router. All devices on your network – PCs, smartphones, tablets, game consoles, smart speakers, TV broadcast boxes, Wi-Fi lighting lights, and anything else you can think of – get their DNS server setup from the router unless Go out of your way to change it on the device. By default, your router uses the Internet Service Provider’s DNS servers. If you change the DNS server on your router, it will be used by every other machine on your network.
Really, if you want to use a third-party DNS server on your devices, we recommend that you change it only on your router. It’s one setting, and if you change your mind and want to change the DNS server later, you can change the setting in one place.
What do DNS servers do?
So, machines only talk about numbers, but people want to use memorable domain names like girlgeniusonline.com or zappa.com. To solve this predicament, the Domain Name System or DNS processes the translation of familiar domain names into digital IP addresses.
Your home network usually depends on the DNS server provided by your Internet service provider. If it is a widely used domain, the DNS server might be storing that information for quick access. Now that the interaction has decreased to numbers, the machines can handle getting the pages you want to see.
As you can see, a domain name system is necessary for all of your internet activities. Any system problems can have consecutive effects on your experience.
For starters, if the DNS servers provided by the ISP are slow or are not properly configured for temporary storage, they can effectively slow down the connection. This is especially true when loading a page that attracts content from many different domains, such as advertisers and affiliates. Switching to efficiency-optimized DNS servers can speed up your browsing, both at home and in the work environment.
How does a DNS Server Help With Privacy?
By default, your computer is likely to access a DNS server controlled by your Internet service provider (ISP), for example, Comcast or AT&T. This means they can easily see the websites you visit – and because they got your name and address as well, they can create a complete profile for you in theory.
If you use a DNS server provided by a different company, they may also log this information … but at least it will be difficult for them to know who exactly is browsing these sites, which could make the data less valuable.
At least one DNS provider has sworn that it will not keep a record: CloudFlare (220.127.116.11) says it will open itself to external auditors to ensure they do not collect data from you.
Why Change DNS Settings?
There is more than one reason to change DNS servers, and while we don’t know the exact configuration of your current connection – so direct comparison is not possible – most people decide to make the change for privacy, speed, security, reliability, allocation, or five reasons.
Regarding privacy, switching DNS servers does not really prevent your ISP from seeing the sites you visit, although it may limit the amount of profile they can create for you to advertisers, depending on their business practices. To really hide your browsing, you need a VPN or encrypted DNS, which is a whole load of additional artwork. If you are interested, Ars Technica has a huge guide here. (Simple DNS encoded on the way, but not yet here).
So avoiding your ISP’s DNS servers may have some privacy benefits, depending on your ISP, don’t expect much – and certainly not anonymous surfing. Alternate DNS providers may also track your activity, although providers like Cloudflare have promised to clear all of their records every 24 hours to protect consumer privacy. In addition, many DNS providers block phishing and malware sites automatically, although your ISP might do that as well.
How to Change a DNS server on a Windows computer

- If you want to set a DNS server for IPv6 connections as well, select “Internet Protocol Version 6 (TCIP / IPv6)”, click “Properties”, and enter IPv6 addresses as well. Click OK when you’re done.
