Question [Q][GT-I9500][DNS] Set DNS on Samsung Galaxy S4 GT-I9500

Hi,

I have a problem on Android phone Samsung GT-I9500.
Samsumg GT-I9500 sends DNS requests to DNS server address obtained via DHCP. But it ignores setup changes in setprorp 1 and setprorp 2.

do it:
Code:
adb shell
# setprop net.dns1 <ip1>
# setprop net.dns2 <ip2>
How to change DNS server?
How to add DNS server?

Info:
Code:
shell@ja3g:/ # getprop |grep dns
getprop |grep dns
