  • DHCP – the ip address is not a subset of the overall range

    I don’t a silly thing.

    In SBS I wanted to extend my exclusion range. It was set at 192.168.0.1 – 192.168.0.9. I fired up the DHCP tool and went to the address pool and deleted the exclusion range.

    I thought I would be able to add this back in with no problem. But when I try to add it in I get the message “the ip address is not a subset of the overall range”.

    I am adding the following values 192.168.0.1 – 192.168.0.15

    Does anyone know how I can fix this ?

    Thanks

    Can you post screen shots of each stage so that we can see EXACTLY what you're doing?

      Here is a screen shot of what I am doing.

      Previously the right hand pane had an exclusion range, it was set at 192.168.0.1 - 192.168.0.9

      To get the foreground window you can see in the screen shot I right clicked in the right hand pane and selected "New Exclusion Range"

      DHCP gives out addresses in the 192.168.0.101 - 192.168.0.149 range and there is no device using any of the extra IPs in the exclusion range (192.168.0.10/11/12/13/14/15)

      Ideas would be welcome.

      thanks

        Well in my mind it makes perfect sense. The DHCP range is 101-149 and you're trying to exclude 1-15 which is outside the range.

        I believe the Exclude is if you wish to exclude some addresses INSIDE the range.

        So what are you trying to do? Allocate 16-149 -- change the range.
        Cheers,

          Thanks rvalstar!

          Your correct...

          I never thought this one through.

          I suspect the exclusion range was set and then the DHCP range was changed at a later date.

          Thanks again !

            The screen shot and follow on description was really what did the trick.

            I was merely a second set of eyes.
