Hi Kraishak
Options are setting sent to the client to configure the client
behaviour. ddns-domainame is a setting to configure how dhcpd server
performs dynamic DNS updates.
option domain-name "example.org";
this is the equivalent of setting the domain function in
/etc/resolv.conf, that is, it is the domain to add to an unqualified
name. So if user looks up the name "foo" it will try "foo.example.org".
See dhcp-options man page for options that are sent to configure the
client.
ddns-domain-name "desktop.example.org";
this is the domain the dhcp server should add to an unqualified name
when forming a fully qualified name for updating in the DNS system. So
host "foo" is to go into DNS as "foo.desktop.example.org". See
dhcpd.conf man page.
So you might put all your clients in a sub-domain, eg laptop "foo" goes
in desktop.example.org. But all your servers are in the top level, eg
server1.example.org. So you would have
option domain-name "example.org";
ddns-domainname "desktop.example.org";
regards,
Glenn
