=> yes of course. BTW the way to set the next server address field
(aka siaddr) in BOOTP/DHCP packet is the Pkt4 setSiaddr() method.

Francis,
Currently, I'm hardcoding 'next-server' in kea.conf. Is it possible to do
it via hook code?

Thanks, Francis. If I want to get rid of hardcoding 'next-server' from
kea.conf and move it to the hooks library by setting the field dynamically,
what it the right way?

=> next-server is a BOOTP/DHCP field, not an option. Note some of these
fields have a corresponding option used for instance when the field
is too small (can't happen with an IPv4 address :-).

> opt = response->getOption(DHO_HOME_AGENT_ADDRS);

=> This option gives a list (vs one) of addresses of the Mobile IP
home agent. So it is something different (but if it makes the client
happy...).
