About this app
The CIDR Calculator enables CIDR network calculations using IP address, CIDR mask (subnet mask), mask bits, maximum required IP addresses and maximum required subnets.
Results of the CIDR calculation provide the wildcard mask, for use with ACL (Access Control Lists), CIDR network address (CIDR route), network address in CIDR notation and the CIDR address range for the resulting CIDR network.

i think we have a problem associated with the Samsung Galaxy Note4 keyboard. My on-screen Numeric keypad has no Dot. So I can't enter a valid IP address. How can this be fixed?

Simple and elegant! Feature suggestion: 1) adding wildecard 2) showing the network id in binary notation with a different color. So that the boundary between net id and host id is more visible.
