IPv4 Subnet Calculator

Subnet calculator and table range for IPv4.

Get exact calculation result from our app to identify IPv4. Enter the IP address and subnet mask without needing to know the network class. The application will tell the subnet class, total subnet, and total hosts per subnet (valid).
What's even more fun is that you can see the subnet id, first host, last host, and broadcast address for each part of the network.

What you will get:
~ network class identification,
~ total subnet,
~ total hosts per subnet (valid),
~ range table containing:
* subnet id,
* first host,
* last host,
* and broadcast addresses
for each part of the network.
