Do ION Meters, 76xx and 8xxx, support “Classless IP addressing”?

Yes

More Information

Basically, Classless IP addressing means that the IP address and the SUBNET mask of the device can belong to different classes i.e. A, B or C.

For example: IP Address is Class B while SUBNET is Class C

IP Addresses:

Class A: 1-126

Class B: 128-191

Class C: 192-223

i.e.: 192.168.1.1 is a class C IP address

Subnets:

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.

 

Examples:

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
