### Description

#### What problem are you trying to solve?
I have a lot of IOT devices in same /23 network. Those devices should be in the range 192.168.110.x and all other devices should be in 192.168.111.x to have a better overview of the IPs.

#### Proposed solution
Most IOT devices can be filtered by MAC address like ESP chips `7C:DF:A1:08:__:__`.
So it would be nice to have multiple ranges for different MAC-Ranges:

```
dhcp:
enabled: false
interface_name: ""
local_domain_name: lan
dhcpv4:
- gateway_ip: "192.168.111.1"
subnet_mask: "23"
range_start: "192.168.110.0"
range_end: "92.168.110.200"
mac_start: "7C:DF:A1:08:00:00"
mac_end: "7C:DF:A1:08:FF:FF"
lease_duration: 86400
icmp_timeout_msec: 1000
options: []
- gateway_ip: "192.168.111.1"
subnet_mask: "23"
range_start: "192.168.111.100"
range_end: "192.168.111.200"
mac_start: ""
mac_end: ""
lease_duration: 86400
icmp_timeout_msec: 1000
options: []
```
