Is there a software like DnsJumper for ubuntu? I want to be able to test and choose from a list of dns server available based on the fastest one possible?
Or maybe just a way to use google open dns as the one provided my isp is real slow?
Hi @_sandhumrt,
When ISP DNS sucks, most typically get to the network device that hands out connection parameters via DHCP and change DNS there so every device gets fed those DNS servers. This would normally be the router.
There are extensive Linux tools for DNS that are not user friendly. Maybe someone can suggest some that are. I can offer a quick commandline to see response time manually:
dig @8.8.8.8 ubuntu-mate.community
Query time is near the end. This tests Google DNS (8.8.8.8) on the lookup of this site.

Thank you, I was able to edit the network connection and enter a list of additional dns servers but my system seems to be using still the one provided by my ISP, I tried the dig command without entering the dns and it shows nameserver 127.0.0.1
How do I force my connection to use the other dns?
Change the DNS server on your router to googles DNS servers
8.8.8.8
8.8.4.4
The second one is their secondary for failover.
The network icon has a “Connection information” that should confirm all it does is add DNS and doesn’t replace them.
When editing or creating a connection, the ipv4 tab has Method: “Automatic (DHCP) Addresses only”. This is the key. The DNS (and Search domains) can now be explicitly set. Separate with commas.
Boy, it sure felt good but I edited out all my profanity. 
I’m not a fan of the concoction known as network-manager which this all is. It runs that stupid dnsmasq instance on 127.0.0.1 so DNS is hidden as much as possible.
Hope this helps.

Yes, that did it, it shows primary dns as the google one now, although the default route is still the same old dns but net speed seems fast, so, I don’t think that affects it anyway.
Thank you so much!
