Public DNS servers (Google DNS, OpenDNS, Quad9, Cloudflare) on Maxis Fiber, Benchmarked
Benchmarked with GRC’s DNS Benchmark tool on Maxis Fiber. Basically, your mileage will vary based on where these servers are relative to your location from your ISPs network. All of them are employing anycast IP addresses, where traffic to them will be routed to nearest server in your region. I prefer these servers rather than ISP provided ones due to their support of DNSSEC, (well except opendns, they have a similar, in function thing going on called DNSCRYPT) which prevent tampering of dns records.
Google’s Public DNS is 8.8.8.8 and 8.8.4.4
Cisco’s OpenDNS is 208.67.222.222, 208.67.220.220 and 208.67.222.1231
Quad9’s is 9.9.9.9, 149.112.112.112 and 9.9.9.10 2
Cloudflare’s is 1.1.1.1 and 1.0.0.1

Notes:
1 Cisco OpenDNS’s Family Shield IP filters some objectional content.
2 Quad9 filters some bad domains. 9.9.9.10 is their no blocking server to check against.
3 Fastest servers on 10.17.0.0/24 are my local servers running a combination of bind9 and dnsmasq
