change the ip address of a connected device

I have the router DHCP set to 100 to 254 but my static ips fall in below 100. So I connected a new device with an assigned IP of .134 but I want that to be .25 in my static ips. How do I do that?

       Terminology: A "static" address is configured on the device itself.
    What you configure on a (DHCP server on a) router is a reserved dynamic
    address, not a static address.  Are you talking about Address
    Reservations on the router, or actual static addresses configured on the
    device itself, or what?

       Huh?  "So"?  Are you using "So" as a verbal filler, or are you saying
    that "I connected a new device" is a consequence of something you said
    before (the actual meaning of "so")?

     

       What is your "a new device"?  How was it "assigned" an "IP [address]
    of .134"?  Again, what do you mean by "my static [IP addresses]"?


       If you're really using reserved (dynamic) addresses, then why can't
    you simply reserve the desired address for your "a new device"?

     

       If you're really using static addresses, then why can't you configure
    your "a new device" with the desired static address?

     

       At least one of us is confused.

      Well I guess I must have bungled that question up. I what I was trying to say the newly connected device got an IP of xxx.xxx.1.134. I have a reserved section in my router where the IP address end in xxx.xxx.1.xx so I want to know, can I change the IP address of xxx.xxx.1.134 to an IP address of xxx.xxx.1.xx? That way it fits in my reserved IP address ending with 2 digits. NO STATIC ADDRESSES TO DEAL WITH! Sorry I confused you.

           If that "xxx.xxx" is actually "192.168", then it's a private address,
        and there's no good reason to hide any of it.

         

        > [...] I have a reserved section in my router where the IP address end

           "section"?  I'm not sure what that means.  Your term or Netgear's?

         

        > [...] can I change the IP address of xxx.xxx.1.134 to an IP address of
        > xxx.xxx.1.xx? [...]

         

           If you configure a suitable Address Reservation on the router, then,
        the next time these devices start up, the client device should get the
        address which was reserved for it (in the DHCP server) on the router.

         

           But creating a new reservation will not, by itself, change the
        address of a running device.  And the router might previously have
        granted that newly reserved address to some other device, so it might
        not be available now.

         

           If you shut everyone down, and start everyone up again, then _all_
        your address reservations should be effective.
