# DNS Performance Test
Shell script to test the performance of the most popular DNS resolvers from your location.
-Includes by default:
- * CloudFlare 1.1.1.1
- * Level3 4.2.2.1
- * Google 8.8.8.8
- * Quad9 9.9.9.9
- * Freenom 80.80.80.80
- * OpenDNS
- * Norton
- * CleanBrowsing
- * Yandex
- * AdGuard
- * Neustar
- * Comodo
- * NextDNS
+The accompanying ipv4 and ipv6 text files contain the redundant servers of notable DNS providers by default, including:
-# Required
+* AdGuard
+* CleanBrowsing
+* Cloudflare (aka 1.1.1.1)
+* Comodo
+* DNS.Watch
+* Google (aka 8.8.8.8)
+* Level3 (aka 4.2.2.1)
+* Neustar
+* OpenDNS (aka 208.67.222.222)
+* OracleDyn
+* Quad9 (aka 9.9.9.9)
-You need to install bc and dig.
+...as well as the redundant servers of these other well-known providers (and many more):
-For Ubuntu:
+* AlternateDNS
+* ControlD
+* DNSFilter
+* Freenom
+* NextDNS
+* NortonCS
+* SafeDNS
+* UncensoredDNS
+* Verisign
+* Yandex
-```
- $ sudo apt-get install bc dnsutils
-```
+13 default domain names are tested, with many others available as toggleable in the accompanying text files, or simply add your own:
-For macOS using homebrew:
+* docker.io
+* github.com
+* gmail.com
+* www.amazon.com
+* www.apple.com

+* `dig` needs to be in the PATH. If you don't have it, the script will provide instructions for where to get it.
+* `bc` is no longer a requirement of this script since being forked. `awk` is used instead for greater wide-spread availability - particularly for Synology. (this need was what initially prompted the creation of this fork)
-To sort with the fastest first, add `sort -k 22 -n` at the end of the command:
