    Handling more than 254 potential IP addresses

    Just installed UltraMon and looks like it's a no go on my network

    7/23/2015 9:36:13 AM ~!~Error~!~Unable to monitor 192.168.0.0/22 because it exceeds 254 IP addresses.

    So, no way to use it then?

    do you really have a home network that is a /22? Is your netmask on all of your devices 255.255.252.0? and not 255.255.255.0? a /22 makes 1,016 ip addresses available on your lan which I can't imagine needing -- and if it is really that big, i'd definitely vlan home automation out to its own subnet, and virtually isolate it, just to reduce the exposure since there are quite a few security issues with HS3 that "trusts" the lan a little too much for a flat network that large.

    If your subnet mask is 255.255.255.0 and all of your devices are in the same class C, IE: 192.168.0.XXX, then you should change the netmask on your plugin to a /24

        what is your network device? Layer 3 switch? Router? Is it /22 by choice or by default?

        /22 is kinda big for a broadcast domain. You could run into issues like broadcast storms with that many nodes in the same subnet. You could break it up into vlans with /24s and route between them. That would reduce the amount of broadcast traffic.

          Just add the following:

          192.168.0.0/24
          192.168.1.0/24
          192.168.2.0.24
          192.168.3.0/24

          Problem solved
          Plug-ins: UltraMon, UltraM1G, UltraCID, Ultra1Wire, UltraLog, UltraWeatherBug, UltraPioneerAVR, UltraGCIR
