There are certain consumer devices which are outliers in protocol conformance.
An example is Samsung bluray players, which require broadcast DHCP responses
(on Ethernet only, strangely
not on Wifi).
By specifying:
config host
option broadcast 1
this will enable the response to be sent as an Ethernet broadcast and not as a
unicast.
