Find your IP range by examining your subnet mask. Most likely, if you are using a simple home network, your IP address begins with 192.168.0 and your mask is 255.255.255.0. This mask means that the address range 192.168.0.1 to 192.168.0.255 is available for assignment in your subnet. Show Comments.
In the first column, locate the range of IP addresses that include the IP address already assigned to your computer. In the second column, you will find the appropriate default router IP address. In the third column you will find the network mask, and the fourth column shows the broadcast address. For example: if your IP address is 128.112.177.234, then the IP address of the default IP router is 128.112.176.1, the network mask is 255.255.252.0, and the broadcast address is 128.112.176.0.
