C is also correct, it does enhance security features.

Wait, does IPv6 really improve security? Sounds too good to be true.

I vaguely recall something about security improvements with IPv6, so option C might be true, but I need to double-check that.

I think option B is correct because one of the main reasons for IPv6 was to increase the number of available IP addresses.

I'm not too sure about option A; I thought IPv4 and IPv6 were separate and didn't really overlap like that.

I remember studying that IPv6 does indeed use 128-bit addresses, so I think option D is definitely true.

I remember learning about IPv6 improving security, so I think I know that one. The rest I'll have to guess on.

The IPv6 address length is definitely 128 bits, so that's an easy one. The other details are a bit trickier, though.

Okay, I know IPv6 increases the address space, but I'm not sure about the other details. I'll have to read the options closely.
