Si les intriga como se compara la performance de diversos providers de 
DNS recursivo, les recomiendo una lectura rápida:

- 
https://medium.com/@nykolas.z/dns-resolvers-performance-compared-cloudflare-x-google-x-quad9-x-opendns-149e803734e5

Hay un test que pueden correr uds individualmente, alcanza con hacer:

1. Clonar un repo de github:

```
yaguaron:scratch carlos$ git clone 
https://github.com/cleanbrowsing/dnsperftest/ dnsperftest
Cloning into 'dnsperftest'...
remote: Counting objects: 24, done.
remote: Compressing objects: 100% (22/22), done.
remote: Total 24 (delta 5), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (24/24), done.
yaguaron:scratch carlos$ cd dnsperftest/
```

2. Correr el test y visualizar resultados (los de abajo son desde la red 
de LACNIC, AS 28000):

```
yaguaron:dnsperftest carlos$ bash dnstest.sh
