Why Change DNS Servers
Changing your ISP’s default DNS servers can grant you:
- Better browsing speed (by resolving domain names faster)
- More reliable service (by preventing fishing or malware)
- Avoid censorship (from governments) and unlock websites, such as AlfaFile.net
If you are using your ISP’s default DNS servers you really should consider changing your DNS provider for a more reliable and secure option. Follow this article to know what is DNS and how to change it. In the end, if you're not happy you can reset it back to the default DNS servers very easy.
What is DNS Servers
DNS stands for Domain Name System and is a protocol, or language, that computers use when talking to each other. Every device on the public Internet has an IP address and DNS is like a language that converts an IP address like 192.168.10.1, into the appropriate domain name, like audiok.info for instance. Like this you don't have to memorize a series of numbers which is more difficult to the average human, instead you only have to know a name.
DSN servers are like a dictionary that converts and delivers information by making the right connection, and who controls the DNS servers can redirect you to the right domain or not. In some cases they can even prevent you from access free knowledge and information, like how some Governments are doing by forcing some ISP's providers to block certain websites.
Public DNS Servers
Your home router is likely set by default to use your ISP’s DNS servers, which may or may not be very reliable. There are a number of third-party DNS servers, however, we strongly recommend OpenDNS or Google Public DNS, preferably opting for the later.
Open DNS offers a neat service but we found some extra connections (mainly due to their more advance customisation options and family packages) and their servers are slower.
Google is one of the most reliable and powerful companies in the world and Google Public DNS servers are faster and very reliable, we advise opting for Google Public DNS.
Every major DNS service has at least primary and secondary servers to ensure that requests will always be answered. When changing DNS server settings, you’ll want to make sure that you specify at least two servers, although you can include more if you want.
Google Public DNS IP addresses are: 220.127.116.11 and 18.104.22.168
How To change DNS Servers in your Router
Log in to the router’s administration panel and look for the DNS page settings. Unselect the "Automatic from ISP", add Google DNS servers and Apply Changes. There's a lot of routers but they all have similar options and the DNS page settings is one of them.
How To change DNS Servers in Windows
Open the Network and Sharing Center and click on the Change adapter settings option, on the left-hand side menu. Right-click on the Ethernet network icon and select Properties from the context menu. When the Ethernet Properties window open, you will need to select Internet Protocol Version 4 (TCP / IPv4) from the list, then click Properties. You will see in the bottom half of the General tab that your PC is set to "Obtain DNS server address automatically”, so you will need to change that by manually adding Google DNS servers and then press OK.
How To change DNS Servers in Mac OS
Open System Preferences and click on the Network icon. Unlock the pane if necessary by clicking on the lock icon and entering your password. Click on the Advanced button, then on the DNS tab. Click the + button and add Google DNS servers, then press OK and Apply.
You can change your DNS servers in the router and in the individual computers connected to the router. Like this when you use your laptop in a different Network, and that network doesn't use Google Public DNS, you will still use Google DNS servers because they are configured in your laptop.
Consider start using Google DNS Servers now for better speed and security. If you have any doubts there's a lot of information out there and you can use Google to find more about it.
