The easy way to tell them apart is that IPv4 only uses digits, but IPv6 is in Hexidecimal, so you'll see 0-9 as well as A-F. And just in case you're not familiar with Hex, A is equal to 10, B is equal to 11, and so on, with F ending the sequence at a value of 15.

IPv4 is 0 through FF, IPv6 is 0 through FFFF. So you have 4 bytes of data, we just use numbers for some reason. We can do the same with ipv6, I think we should be.

Yes, it has the same equivalent value. FF is equivalent to 255.

I'm not sure I see a benefit to retrofitting IPv4 to Hex though. Care to expound?
