AD DHCP (im pretty sure this is on topic)

  1. with a DHCP server in an ad domain, i need to understand one thing...

    we have multiple vlans on the network and all will have computers on them
    with different ip subnets. how do i configure DHCP scopes when this is the

    in other words, i need to make sure that a client on 10.64.4.x can ONLY get
    an address from the 10.64.4.x scope, and the 10.65.4.x machines get
    addresses from the 10.65.4.x scope. i cant see how to avoid a 65 machine
    randomly getting a 64 address.

    thank you

  2. Hello,

    do you plan to multihome the dhcp server, or will you use dhcp relay agent ?
    In both case, dhcp will send a DHCP lease with an IP that match its ip
    interface from which it receive the lease request, or based on the ip of the
    relay agent.

    Do not make global scope ;)

  3. where would the dhcp relay agent be? and how is this configured? (is it on
    the switch/router that holds the vlan?)

    no the server is not multihomed

  4. Yes, on router, or Windows server if present on both network.

    Do you have any network router or Windows server both present on networks ?

    Else you may use the network's card software to use tagged vlan (multhome
    the dhcp server through one network card)

  5. i believe the router/switch has the relay agent... if not ill need an RRAS
    server on each subnet, correct? off topic but, when the relay agent is on a
    switch/router, does it have to be configured? or is it automatic when you
    create the vlan?

    In the relay agent you define wich DCHP address to contact.

    I hope that the information above helps you.
    Have a Nice day.
