OK, found your previous post here: http://www.multitech.net/developer/forums/topic/dns-configuration-on-mlinux/
I have it set up similr to your recommendation:
# Wired interface
auto eth0
iface eth0 inet static
address 192.168.2.100
gateway 192.168.2.1
netmask 255.255.255.0
I have Internet access (ping IP) but not DNS (“us1.loriot.io” translation).
