I would like to ask how can I configure a dhcp to work from - for example. Is this a software or hardware tweak? Also do I need a special server/router/software? Thank you in advance.

  • If you need mutliple ranges within a subnet and use ISC DHCP (or alike), this should answer your question. There are different implementations out there, Wikipedia names a few (OSS only) but there are several commercial implementations (i.e. Microsoft or cisco) as well.

Just configure your DHCP server with scope - and subnet mask Here's an example how to do it with Microsoft DHCP server:

DHCP scope on MS server

.255.255 is the broadcast address, so that cannot be assigned to a device.

  • That's what I needed, is this software/hardware specific? Is it applyable to routers? Tnx! Jun 17, 2015 at 13:06
  • No, it's not specific to Windows DHCP server, that was only used as an example. You should be able to do this with any DHCP service. Jun 17, 2015 at 13:24

    If you need to know whether this is applicable to devices, you need to name the device. For example my home DSL router can't do /16 networks at all. Jun 18, 2015 at 14:17

I do not think that would be possible. Remember that is a class C address range which defaults to a subnet mask. For the end would be So you would most likely define different ranges I think. to to and so on

  • I think @Arimo's answer is more like what you need. Jun 17, 2015 at 12:25

    Classful addressing really isn't a thing anymore. Jun 17, 2015 at 12:48
