Usually you know it because you set it. And if you're not involved in setting it, you usually have no actual need to know it. What are you needing it for? What are the devices involved? If this isn't an academic question, what business problem is involved? -- Tom

If you have a home router, then have the range of 192.168.xxx.xxx.  If you are working with it, then I suggest you ask your NetOp section.

Just look at the network configuration for your own PC (ipconfig in windows), you will see the IP address and subnet mask. From this you can deduce the IP range available on your network. However, as Tom says, this is not really useful information, unless you manage the network, in which case you should already know this.

The IP calculator calculates the network and broadcast addresses that a given IP address is associated with. The calculations are based on RFC 1219 compliant addresses. A maximum of three decimal characters (0-9) per box with a decimal value of between 0 (zero) and 255 is required. If the value is 0, please put in a 0. The network prefix length is assumed in hex; a maximum of 2 hex characters are allowed.
