[Dnsmasq-discuss] Linux and MacOS cannot get DHCP address

[Chris Blake]

Greetings community,

I have done a brief search through the archives and cannot find any
answers, perhaps I have overlooked something.

On our network all our Windows hosts do not have any issues getting a
DHCP address from dnsmasq, but Ubuntu machines and MacOS do not.

My dnsmasq log file tails as follows while my Ubuntu desktop is trying
to connect :

If I have overlooked something in the archives please point me in the
right direction, or possibly shed some light as to why it is only the
Ubuntu and MacOS machines that have this issue.
