Handling more than 254 potential IP addresses

[macrho]

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

It's really a /22
so no possibility of support with that setup, oh well

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
