    [Misc] IR 3570 Network issue IP changing it self

    Hello all,

    I had delivered IR3570 today and I was having problem with networking the copier.
    The place where the copier was delivered had recently opened and the employee or the manager didn't have any idea how the network was set up.
    Although I did get the printer driver installed I wanted to get some feedback from y'all about the issue I had.

    First thing I did was input the ip address that was available (192.168.1.205) along with subnet mask and the default gateway.
    After I rebooted the machine the ip changed automatically to 192.168.1.196 and the DHCP was highlighted when it wasn't before the reboot.
    I also noticed that the DNS field was filled in when it was cleared before the reboot.
    I eventually got the machine to get respond after unchecking the DHCP button and clearing the DNS.

    My question is
    1. Why and how did the ip address change from what was assigned
    2. Why and how did the DHCP highlight by itself

    I've had this type of issue several times and it just drives me crazy.
    Appreciate the response in advance.

    Thanks,

      In this instance I would leave DHCP on and get the customer's IT to create a reservation in DHCP for the machine using the MAC address. Problem Solved.

      (Ideally the IP address should be excluded from the DHCP pool even if you assign it statically to the device.)

          If the DHCP button is selected it does over ride any manually configured entry. Pain I know

          As above, has outlined best practise for DHCP reservations and exclusions.

          Otherwise have it on a static IP address and exclude from the DHCP scope.

          Enjoy

              What I don't get is why the machine select DHCP (highlight) upon reboot.
              When I spoke to the person that worked on the network told me the static ip was used for cctv and dhcp for computers
              I would ask my bosses at work but its really difficult to get a straight answer from them.

              Thanks for the replies

                  Machines are not so perfect. Things like this may happen. Start by upgrading your machine to latest versions.

                      Just Try This -

                      System Setting -> Network Set. -> TCP-IP set. -> DNS S. St. -> DNS Dynamic Update

                      Put OFF this Item

                      So, the machine would not able to automatic update its DNS settings when connected to a network.

                          Depending on the version of the server, DHCP handles the DDNS updates

                          Deselect DHCP, or put a reservation in the DHCP scope via the copiers network MAC

                          Either way - Job done
