DNS Resolver
CloudFlare announced privacy-first consumer DNS service.
IP of CloudFlare public DNS servers are
1.1.1.1 1.0.0.1
So far i was using Google Public DNS servers as my resolver.
8.8.8.8 8.8.4.4
Quad9
Quad9 is from IMB and Global Cyber Allience.
9.9.9.9
Other public DNS server is OpenDNS
208.67.222.222 208.67.220.220
All these DNS servers have good connectivity in india. I get ~65 ping to these serves, that is normal for indian servers.
On linux you can configure DNS server by editing file
vi /etc/resolv.conf
Add
nameserver 1.1.1.1 nameserver 8.8.8.8 nameserver 9.9.9.9
