This role manages the integrated dnsmasq DHCP / DNS / Radvd and DHCPv6 Settings. Managing odhcp, bind or other alternative packages is currently not supported.
Global parameters are documented in the OpenWrt Wiki. OpenWrt utilizes dnsmasq. This is how the Ansible Variables look like.
openwrt_dhcp_dnsmasq_<<parameter name>>
for example
openwrt_dhcp_dnsmasq_filterwin2k
This is an example of how to define a dhcp pool.
openwrt_dhcp_poolshost:
- name: "lan"
ignore: "0"
interface: "lan"
start: "100"
limit: "150"
leasetime: "12h"
dhcpv6: "server"
ra: "server"
ra_management: "1"
ra_default: "1"
domain:
- "example.com"
dhcp_option:
- "6,10.10.133.111"
dns:
- "2620:fe::fe"
- "2620:fe::fe:9"
ra_flags:
- "managed-config"
- "other-config"
You can make definitions on group layer. This is not defined within the group itself but in the allhosts group (e.g. in ./host_vars/allhosts.yml) like this.
openwrt_dhcp_poolsgroup:
testgroup:
- name: "Guests"
start: "100"
end: "220"
interface: "eth0"

The names of the leases may not contain spaces.
IPv4 example:
openwrt_dhcp_leases:
- name: "voiptelefon1"
mac: "00:04:13:aa:bb:cc"
ip: "10.10.129.91"
leasetime: "96h"
IPv6 example:
openwrt_dhcp_leases:
- name: "voiptelefon2"
duid: "fefefefefefefefefefefe"
hostid: "fee"
leasetime: "96h"
Dual Stack example:
openwrt_dhcp_leases:
- name: "voiptelefon1"
mac: "00:04:13:aa:bb:cc"
ip: "10.10.129.91"
duid: "fefafefaefefafefafefa"
hostid: "fea"
leasetime: "96h"
