Here is the complete guide to change DNS server. I am explaining it step by step using pics so that you can understand it easily.
Change DNS Server:
First of all RIGHT CLICK on the network icon and select Open Network and Sharing Center. See below pic
Now CLICK on Local Area Connection and then pick properties. See below pic
Doing step 2 will open a new dialog box. Select Internet Protocol Version 4 and then click on properties. See below pic
Now select “Use the following DNS Server Addresses” See below pic
Now here you will get 2 boxes to enter DNS Server.
- Preferred DNS Server
- Alternate Server box
Put 220.127.116.11 in the Preferred DNS Server box
and 18.104.22.168 in the Alternate DNS Server box
then select ‘Validate settings upon exit’ and CLICK OK. See Below Pic.
DONE All The Best!
