    I am going to change our internal ip range and would like to have more
    than 253 addresses avaliable. Would it be better to go with a
    supernet class C 192.168.0.0/23 setup or or go with a class B
    172.20.0.1/23 configuration. We are running Windows 2003 servers and
    all of the workstations are 2000 sp4 and XP Pro sp2.

    Thanks for any help.

    It would be best to create multiple Class C networks.

    When you say multiple Class C networks are you talking about two Class
    C networks split by a router? Just wondering because at the present
    time I have about 200 devices and I wanted extra IP's because I will
    be implementing a VPN for mobile users that will pull IP's from a DHCP
    server and I wanted enough to go around with some extra room on top of
    that.

    Thanks

    Yes that is what I meant, but since you'll be using VPN, you can do can
    assign a completely different subnet (from the VPN device) to the VPN
    clients and allow that traffic to your internal network.

    I would second that. Using the DHCP option for remote clients was
    designed to allow easy setup for people with limited networking knowledge.
    Because the remotes are in the same IP subnet, the server acts as a proxy
    for them on the LAN.

    In anything other than a simple one-segment LAN, put the remotes in
    their own subnet and route them just as you would route an additional LAN
    segment.
