[Dnsmasq-discuss] Dnsmasq-discuss Digest, Vol 183, Issue 13

[Dave Sullivan]

Hi Matthias,

We tried dhcp option 119 as well and didn't see anything added.

So still confused on here on how to get to this to work.

It seems like it is only taking additional search items from
/etc/resolv.conf

Thanks,

Dave
