What is DNS?

DNS [ Domain Name System ] is the service that translates the site addresses into IP addresses so that web servers can understand. When you type a web address in your browser, a DNS server will find the IP address that is linked to it so the correct site will be opened. It is important to know those large websites such as Google and Facebook use a pool of IP addresses, not just one.

Your ISP gives you a DNS that is configured in your router. However, you aren’t forced to use that one unless you have that in your contract. Switching to another DNS can get you more speed and security. If you don’t know which DNS server you are currently using just follow these steps to know.

Go to Network and Sharing Center then click on the name of your active network.

Then click Details.

You’ll find the DNS easily.

Or you could use cmd and type

// WP CODE

ipconfig /all

then look for DNS Server.

Where can you find alternative DNS servers?

You can choose what you want but for me and several other people, the best two are OpenDNS and GooglPublic DNS. If you choose to use any of those two this could really help you get more speed and improve your security.

Google Public DNS IP addresses (IPv4) are:

// OUTPUT CODE
8.8.8.8     “Primary”
8.8.4.4     “Secondary”

OpenDNS IP addresses (IPv4) are:

// OUTPUT CODE
208.67.222.222     “Primary”
208.67.220.220     “Secondary”

How to change your DNS?

Go to Network and Sharing Center then click on the name of your active network.

Then click Properties.

Click on Internet Protocol Version 4 (TCP/IPv4) to highlight it then click Properties.

If you have a DNS already there write it down to use it again just in case something wrong happens.

Select Use The Following DNS Server Addresses
Enter the DNS Addresses and The Alternative one.
Click OK and restart your PC.

That’s it! Have fun with what you’ve learned today!
