I was just curious to know what DNS server my phone used. So I launched a terminal emulator and I entered:
$ cat /etc/resolv.conf nameserver 184.108.40.206 nameserver 220.127.116.11
As you can see, my phone uses 18.104.22.168 and 22.214.171.124 as DNS servers (Google Public DNS servers).
At home (Wifi), my router is configured to give OpenDNS' servers through DHCP. But, on my phone,
cat /etc/resolv.conf returns the same output. Same thing with 3G. And, even if I disable both Wifi and 3G, and then reboot the phone, it still uses Google's Public DNS servers.
I don't remember having changed
resolv.conf or installed any application to change it.
My phone is an HTC Desire with CyanogenMod 126.96.36.199 (Android 2.3.7).
Can someone explain me why my phone uses Google Public DNS? Is it a common configuration for any Android devices, or CyanogenMod ROM?
