Configure DNS server on Android

Option 1: Settings way

Change DNS configuration from settings apps (but unfortunately some apps like Chrome will ignore our DNS server)

Option 2: DNS over VPN

Using rethinkdns app we can control this:

1. Change DNS settings to "Other DNS"

2. Select "Proxy DNS" (DNS 53)

3. Create a new entry pointing ot your local DNS server host

4. Launch the VPN

You can check whether DNS spoofing works by going to Google Chrome and visit chrome://net-internals.
