But that's the point - the internet addresses map to user friendly names which we use for browsing. So, really, what does IPv6 really bring to the table over IPv4?
IP addresses are used by all connected devices, not just those hosting websites. In fact, a lot of different websites can and are hosted on one server, technically linking to the same IP address. The number of available IP addresses in IPv4 is running out because there are only so many combinations you can make in a 0.0.0.0 to 255.255.255.255 range. IPv6 brings LOADS more addresses.
