Subnets not to be used with IPA or Iris panels
The E-IPA / IRIS panels used the following subnets (internally)
10.0.0.0/30 (IRIS and IPA)
IPs between 10.0.0.0 to 10.0.0.3
10.0.0.4/30 (IPA only)
IPs between 10.0.0.4 to 10.0.0.7
subnet /30 == 255.255.255.252
We recommend our customers not to use a network starting at 10.0.0.0.
