Hi Chris,
Thanks, that last line shouldn’t be there so I removed it.
The IPv6 prefix has this format:
Now take a look at this address:
2001:DB8 is the ISP prefix, what comes next is the IPv4 address.
192.168.1.1 in hexadecimal is C0A8:0101, but I don’t have to embed the entire IPv4 address. I can forget about 192.168.1. (those are the common bits), and only embed .1 in the IPv6 address, which is how we end up with 2001:DB8:100:
What comes after 2001:DB8:100: is the subnet, I just picked one (:10).
On the outside domain part, it should be 192.168.1.1 (copy paste error, sorry 
) It has been fixed!
