Extend DHCP Range

I have a simple DHCP range .

option routers 192.168.1.1;

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.60 192.168.1.129;
range 192.168.1.150 192.168.1.199;
}

So I want to add a range 192.168.2.1 -> 192.168.2.254
so I did this:

subnet 192.168.1.0 netmask 255.255.254.0 {
range 192.168.1.60 192.168.1.129;
range 192.168.1.150 192.168.1.199;
range 192.168.2.1 192.168.2.254;
}

then tried to restart the dhcpd server… This did not work. How do I get more dhcp addresses ?

Thanks,

Jerry

  • subnet 192.168.0.0 netmask 255.255.252.0

    would let you have .0.x .1.x .2.x and .3.x and so your ranges are included.

    Is that what you want?

  • The first thing that jumps out to me is that you cannot have a /23 subnet which starts at .1. In other words – 192.168.0.1/23 is not valid. You can use either 192.168.0.0/23 or 192.168.2.0/23.

    If you want to use .1 and .2 as shown, then they must be two separate /24 subnets. That wil require some router configuration in addition to the DHCP setup.
