Sub-pool or pool hierarchy

[Sten Carlsen]

I still think it is completely doable. I include my own dhcpd.conf:

~~~~~~~~~~~~~~~~~~~~
# File: dhcpd.conf
# Computer: Revo.s-carlsen.dk
#
#
# Global parameters
max-lease-time 1800;
default-lease-time 1800;
# Common settings.
log-facility local0;
server-name "revo.s-carlsen.dk";
get-lease-hostnames false;

# ddns update.
ddns-update-style interim;
deny client-updates;

# class definitions
class "gateway-1" {
         match hardware;
       }


class "gateway-2" {
         match hardware;
       }


class "gateway-4" {
         match hardware;
       }



# Subnet Declarations
shared-network hjemme{
    authoritative;
    subnet 192.168.16.0 netmask 255.255.255.0{
        option lpr-servers        192.168.16.38;
        option domain-name        "s-carlsen.dk";
        option domain-name-servers    192.168.16.32;
        option subnet-mask        255.255.255.0;
        option ntp-servers        192.168.16.32;
        # B-NODE: Broadcast - no WINS
        option netbios-node-type 1;
        option smtp-server 192.168.16.32;
        pool{
            option routers            192.168.16.1;
            allow members of "gateway-1";
            range 192.168.16.50    192.168.16.127;
        }
        pool{
            option routers            192.168.16.2;
            allow members of "gateway-2";
            range 192.168.16.128   192.168.16.199;
        }
        pool{
            option routers            192.168.16.4;
            allow members of "gateway-4";
            range 192.168.16.200   192.168.16.240;
        }
    }
    subnet 192.168.61.0  netmask 255.255.255.0{
        max-lease-time 300;
        default-lease-time 150;
        pool{
            deny known-clients;
            deny members of "gateway-1";
            deny members of "gateway-2";
            deny members of "gateway-4";
            range 192.168.61.100   192.168.61.150;
        }
    }
    subnet 192.168.122.0 netmask 255.255.255.0{
    }
}

include "/etc/dhcp/subclass.conf";
~~~~~~~~~~~~~~~~~~~~

As you see I have a shared network, my unknown clients go to there and
have no router or anything.

My known clients are grouped in those 3 classes, in my case by a match
hardware but anything could be used.

In my main subnet 192.168.16.0/24 I have 3 pools each with its own
router and range.

My thinking is that if you simply use the same setup, except your class
definitions are based on the hostname, it should work the same.

This is a working setup, this mail is written from the network set up
this way.
