Code that generates MD5 hashes from IPv6 addresses giving differant answers?

Hello,

You are correct, the u is for unsigned character. It originated in C as a data type, originally for an 8 bit byte, where you wanted to use the full 255 possible values.
Without it, the range would be  -128 to 127.

it's for unsigned (int is implied ... 32 bit in common platforms) in C.  and works that way in Py, too:
