> At this point I was interested and decided to take a look if the Wii U implementation suffers from the same issue. To my surprise the Wii U implementation looks something like this instead

So, how does the author got hold of Wii's code, is it publicly available or was it some kind of reverse engineering?

Reverse engineering:

    After reverse engineering parts of the Wii Us' NET stack for another project I was working on, I realized it's using a modified version of NicheStack.

That part of the code was reproduced from the author’s understanding of the assembly.

It's also possible it was released depending on the DNS server license

Since a lot of embedded devices these days rely on software like Webkit they typically have a firmware release zip somewhere for license compliance
