Hello all,

        I am attempting to supernet my network here at the school as I run
out of IP address fairly frequently.  Here are the pertinent parts of
dhcpd.conf

Current:
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.1 192.168.1.48;
range 192.168.1.50 192.168.1.100;
range 192.168.1.111 192.168.1.121;
range 192.168.1.123 192.168.1.141;
range 192.168.1.155 192.168.1.199;
range 192.168.1.220 192.168.1.240;
option routers 192.168.1.254;
}



option broadcast-address 192.168.1.255;
option subnet-mask 255.255.255.0;


Proposed:
subnet 192.168.1.0/22 netmask 255.255.255.0 {
range 192.168.2.1 192.168.2.254;
range 192.168.3.1 192.168.3.254;
range 192.168.4.1 192.168.4.254;
option routers 192.168.1.254;
}



option broadcast-address 192.168.252.255;
option subnet-mask 255.255.252.0;


After making these changes to dhcpd.conf dhcpd does not restart.

I intentionaly left 192.168.1 192.168.1.253 out as it is where all of my
current statically assigned addresses live.
