Do ION Meters support "Classless IP addressing"?
Issue
Classless IP addressing means that the IP address and the SUBNET mask of the device can belong to different classes.
There are three classes of IP addresses: A, B, and C. Each class covers a different of the range of the first octet of the IP Addresses:
Class A: 1-126
Class B: 128-191
Class C: 192-223
For example, 192.168.1.1 is a class C and 126.168.68.10 is class A IP address.
The classes for the Subnet mask is a little different. The classes are as follows:
Class A: 255.0.0.0
Class B: 255.255.0.0
Class C: 255.255.255.0
It is possible to use a Subnet that is greater than the minimum values listed above. However, it would be inconsistent to use a Subnet lower than those values.
Below are examples of appropriate and inappropriate examples of IP/Subnet pairs:
Right: IP 10.168.68.10 Subnet 255.0.0.0
Right: IP 10.168.68.10 Subnet 255.255.248.0
Wrong: IP 192.168.1.1 Subnet 255.0.0.0
