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.
IPv4 was the first standard for IP addresses. 192.168.0.1 is a common example of an IPv4 address. The most recognisable IP addresses are in the range 192.168.0.1 to 192.168.0.255 because these tend to be the ones we use at home. An IP address is a sequence of four blocks of numbers. Each of these blocks is a value between 0 and 255, which means that each block has 256 possible values. So with four blocks allowing for up 256 possible values, IPv4 allowed for around four billion unique addresses, which seemed like a huge amount.
