So then, 255 is the maximum IP.
Your IP (on IPv4) cant be above that because, the packet is only 32 bit and it is sliced into 8bit segments x.x.x.x 8 bit is 0-255, like 8 bit color is 256 colors, and 16 bit is (0-65536) and 32 is 5 billion, so there is a maximum of 5 billion IP addresses on the internet, so when 5/6 of the world population get online, we've got problems!!!
So there is IPv6 (How may bit addresses is that?)
