|
|
### Option: `domain` (required)
|
|
|
|
Your network domain name, e.g., `mynetwork.local` or `home.local`
|
|
|
|
### Option: `dns` (required)
|
|
|
|
The DNS servers you DHCP server gives to your clients. This option can
|
|
contain a list of servers. By default it is configured to have Google's
|
|
public DNS servers: `"8.8.8.8", "8.8.4.4".
|
|
|
|
### Option: `default_lease` (required)
|
|
|
|
The default time in seconds that the IP is leased to your client.
|
|
Defaults to `86400`, which is one day.
|
|
|
|
### Option: `max_lease` (required)
|
|
|
|
The max time in seconds that the IP is leased to your client.
|
|
Defaults to `172800`, which is two days.
|
|
|
|
### Option: `networks` (one item required)
|
|
|
|
This option defines settings for one or multiple networks for the DHCP server
|
|
to hand out IP addresses for.
|
|
|
|
At least one network definition in your configuration is required for the
|
|
DHCP server to work.
|
|
|
|
#### Option: `networks` -> `subnet`
|
|
|
|
Your network schema/subnet. For example, if your IP addresses are `192.168.1.x`
|
|
the subnet becomes `192.168.1.0`.
|
|
|
|
#### Option: `networks` -> `netmask`
|
|
|
|
Your network netmask. For example, if your IP addresses are `192.168.1.x` the
|
|
netmask becomes `255.255.255.0`.
|
|
|
|
#### Option: `networks` -> `range_start`
|
|
|
|
Defines the start IP address for the DHCP server to lease IPs for.
|
|
Use this together with the `range_end` option to define the range of IP
|
|
addresses the DHCP server operates in.
|
|
|
|
#### Option: `networks` -> `range_end`
|
|
|
|
Defines the end IP address for the DHCP server to lease IPs for.
|
|
|
|
#### Option: `networks` -> `broadcast`
|
|
|
|
The broadcast address specific to the lease range. For example, if your
|
|
IP addresses are `192.168.1.x`, the broadcast address is usually `192.168.1.255`.
|
|
|
|
#### Option: `networks` -> `gateway`
|
|
|
|
Sets the gateway address for that the DHCP server hands out to its clients.
|
|
This is usually the IP address of your router.
|
|
|
|
#### Option: `networks` -> `interface`
|
|
|
|
The network interface to listen to for this network, e.g., `eth0`.
|
|
|
|
### Option: `hosts` (optional)
|
|
|
|
This option defines settings for one or host definitions for the DHCP server.
|
|
|
