Subnet Calculator

Subnet Calculator - Network Tools

The Subnet Calculator enables subnet network calculations using network class, IP address, subnet mask, subnet bits, mask bits, maximum required IP subnets and maximum required hosts per subnet.

Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet address range for the resulting subnet network and a subnet bitmap.

==Notes about the Subnet Calculator========

1. The subnet calculator implements a classful / classed IP addressing scheme where

the following rules are adhered

2. The subnet calculator allows the use of a single subnet bit - for example, a class C

address with a subnet mask of 255.255.255.128 is permitted.

3. The subnet calculator allows a subnet ID to have its final octet equal to the final octet

of its subnet mask - for example, a class C network address of 192.168.0.192 with a

subnet mask of 255.255.255.192 is permitted.
