what does ip address mean
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.
