Hi,
I was doing some testing with dhcp-server-4.4.1, and although option
netbios-name-servers is configured, is not being pushed to the client.
This is the tcpdump that I see (verified also with wireshark) and
netbios-name-servers is no where to be found in the DHCP Offer.

Am I looking in the wrong place or is it really not working?
thanks.
