Hi,

Check the output of route and ifconfig. Maybe you're encased in a VPN
due to the bitmask thing (which I'm not familiar with).

Lets get this right Bitmask is not a "VPN" program in they way most people
would think it, you have installed a encryption program to hide what you
are doing for some reason.

it clearly states that DNS WONT use public DNS servers .
https://bitmask.net/en/help/vpn/linux#dns

As they say

"For these reasons, Bitmask will ensure that all DNS requests that your
computer makes are rerouted to the DNS server of the provider."

so there is your prolem
