UNICAST and BROADCAST mode response

[Vic Berdin]

Hi everyone,

 

 

I notice that my server (isc-dhcpd-4.2.1) can send replies either in
BROADCAST or in UNICAST mode (see wireshark screen capture). But most of the
time, the replies are in UNICAST. I am familiar with the "always-unicast"
config setting. However, if such a parameter is not present, how/when does
the server sends its OFFERs/AKCs/NAKs in BROADCAST mode? Similarly, is there
an equivalent "always-broadcast" in isc-dhcpd-4.2.1? 

Any info is very much welcome.

 

 

Thanks in advance,

Vic
