I have a single host on my network that I want to have a different DNS entry for than the rest of my network.  I have tried playing round with various variables in /etc/conf/dhcp, however I can not get it to work.  Is this possible and if so can someone please shed some light on how to do it?

this is what I have in my config so far, I have tried 'option nameserver 4.4.4.2'  'option dns 4.4.4.2' and even 'option 'resolvfile' '/etc/testresolv.conf'  I can't get it to work.

/etc/conf/dhcp:
config host
        option name host1
        option mac  XX:XX:XX:XX:XX:XX
        option ip   10.10.0.15
       

TIA,
BG
