[Dnsmasq-discuss] DHCP: Allocate from different IP pools depending on MAC address

[Olivier]

Hello,

I've got several Debian hosts using ISC DHCP server.

In those, I'm currently using the following feature:
"when a requesting host MAC address ends with 00, use group 0
when a requesting host MAC address ends with 01, use group 1
when a requesting host MAC address ends with 02, use group 0
when a requesting host MAC address ends with 03 use group 1
...
when a requesting host MAC address ends with ff, use group 1
for hosts from group 0, allocate from pool 192.168.1.1-50
for hosts from group 1, allocate from pool 192.168.1.101-150"

In dhcpd.configuration, this translates to
class "guest0" {
   match suffix(hardware, 1);
}

class "guest1" {
   match suffix(hardware, 1);
}

subclass "guest0" 00;
subclass "guest1" 01;
subclass "guest0" 02;
subclass "guest1" 03;
...
     pool {
         allow members of "guest0";
         range 192.168.1.1-50 192.168.1.50;
      }
      pool {
         allow members of "guest1";
         range 192.168.1.101 192.168.1.150;
      }

As you may guess, requesting devices are unknown when DHCP server is
configured and using two different IP pools allows rough dispatching
devices among available WAN links.

Is it something that can be reproduced with Dnsmasq ?
Suggestions ?

Cheers
