    I currently have a 192.168.1.x/24 network that is saturated. While I'm
    reworking the network architecture, I think I need to change to a 16
    bit netmask. From the research that I've done, it looks pretty
    straight-forward to change a server's (running AD) IP address, so that
    gives me hope it's not too hard. I plan on keeping the server IP the
    same, but changing the netmask from to

    Any words of caution? I know I'll have to "update" this in my DHCP
    range, on all printers/devices and so on.

    If you are doing a rework of your network, why not simply create a
    second /24 subnet an route between them? That way you do not ned to change
    anything in the existing network or the existing DHCP scope. Just set up a
    new scope for the new subnet.

    Thanks - hadn't thought of that. I guess I would setup my Sonicwall so
    that it knew both /24's were "local" - seems like that would really
    increase the work-load on the router/sonicwall though wouldn't it? All
    of a sudden any packets for the new /24 would have to bounce off the
    router and back onto the network as opposed to the switches handling
    them right? Or, am I off on picturing how that would work. It's hard
    to visualize packet movement since I've not set something up like that

    Seems like moving to a /16 still seems like the best option That would
    go from a to a setup. Maybe I'm not seeing
    your suggestion clearly.

    That depends on what you use to route between the subnets. If your switch
    supports it you could use VLANs. You could use the Sonicwall and two
    switches if the Sonicwall has two LAN ports. Or you could use a separate LAN
