Today I looked into IPv6 and what it is. Apparently IPv6 is the new Internet Protocol version which will replace IPv4. Don't ask me where IPv5 went. It never entered the public realm. The reason IPv6 was created is to solve the IP address shortage. IPv6 has a 128 bit address space unlike IPv4 which uses 32 bit. This means that there are 4 times more IP addresses available. IPv4 has 4,294,967,296 addresses available so multiply that by 2 for or do 2 to the 128 power and you get a big number. I can't offer much more right now since I'm still reading into the technical stuff about IPv6 but apparently it is more efficient than IPv4.
Also I looked a bit into creating a walled garden which is where you are redirected to a login page when accessing a wireless internet connection. It looks simple enough, but only if you have the right tools and right now I'm still looking into that.
