I am using those:
For IPv4: 18.104.22.168 and 22.214.171.124
For IPv6: 2606:4700:4700::1111 and 2606:4700:4700::1001
but before several minutes the access to internet was blocked, I tried to restart my pc, restart my internet adapter driver in windows but no lock.
So I decided to return my DNS settings to default, and it worked, now I have access to internet, What happened?
I am in Saudi Arabia if you need this information.
