man dhcpd.conf
search in it for "address" and "listen"
configure listen parameters in /etc/dhcpd.conf

Put your listening address for the server after the local-address
option.

e.g. local-address 192.168.200.255

e.g. subnet 192.168.200.0 netmask 255.255.255.0

You might have another DHCP server on your LAN.  You have to configure
each to work separately.

You might have another DHCP-like server on the same computer, you'd have
to stop one, or configure them to listen on different interfaces.

Post your /etc/dhcpd.conf file if you need more help.

Here's an example, with *SOME* of your addresses inserted into it, it
might not work for you without some changes:

--------------------------- begin ---------------------------------

authoritative;
allow                   client-updates;
include                 "/etc/rndc.key";
default-lease-time      21600;  # 2 hours
max-lease-time          43200;  # 24 hours
min-lease-time          30;     # 30 seconds 
server-name             "boss";
local-address           192.168.200.255

## DHCP + dynamic DNS server options (next 4 lines)
#ddns-domainname         "lan.example.com.";
#ddns-rev-domainname     "in-addr.arpa.";
#ddns-update-style       interim;
#ddns-updates            on;

option domain-name      "lan.example.com.";
option ntp-servers      lan.example.com;
option ip-forwarding    off;

shared-network lan.example.com {

        subnet 192.168.200.1 netmask 255.255.255.0 {

                range 192.168.2.2 192.168.200.253;

                option routers                  192.168.200.1;
                option subnet-mask              255.255.255.0;
                option broadcast-address        192.168.200.255;
                option domain-name-servers      192.168.200.1;

## For DHCP + dynamic DNS (next two zone statements)
#                zone lan.example.com. { 
#                        primary 192.168.200.1;
#                        key rndckey;
#                }
#
#                zone  1.168.192.in-addr.arpa. {
#                        primary 192.168.200.1;
#                        key rndckey;
#                }
 
       }
}

-------------------------- end -------------------------------

You can delete the # DHCP + dynamic DNS sections if you don't have DHCP
and DNS servers talking to each other.  If you do, then write something
like them, without hashes commenting them out.
