DHCP server 2012 r2 and subnet scope RRS feed

  • Question

  • HI

    i migrated my server DHCp from 2008 to 2012 r2 and all work fine.

    My network is class C :


    and i have a dhcp scope and work fine

    But now i have a problem.. the scope is almost full and I have to add IP phones on this network.

    If try to add scope , for example, 172.16.10.X --> i can't because caused the conflict with the scope 172.16.8.X

    From what i understand, there are two solutions:

    Solutions 1

    Resubnetting my network ,for example to


    change the subnet on my devices (grr... more more devices) 

    change the subnet on the actuall scope (172.16.8.x from to

    create another scope in my dhcp server 172.16.16.X 

    all things should work

    Solutions 2:

    use another dhcp server.. for example the gateway dhcp.. with macaddress reservation.

    Please can you help me in this problem?
