This is an example of how to use a linux dhcpd DHCP server to hand out ip address leases and specify the TFTP option 150 for VoIP phones in the dhcpd.conf config file. # /etc/dhcpd.conf ddns-update-style interim; ignore client-updates; # Define Custom Options option option-150 code 150 = ip-address; # Global Config option ip-forwarding off; option nis-domain "domain.local"; option domain-name "domain.local"; default-lease-time 21600; max-lease-time 43200; subnet 192.168.117.0 netmask 255.255.255.0 { option routers 192.168.0.1; option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; option domain-name-servers 192.168.0.10; option nntp-server 192.168.0.10; option time-offset -18000; option option-150 192.168.200.10; # TFTP Custom Option next-server 192.168.200.10; # TFTP Boot range dynamic-bootp 192.168.0.200 192.168.0.249; } Enjoy.
