Hi Richard,

many thanks for the review - already looking forward for part 2.

After quickly browsing your comments, most seem to be more or
less editorial, except for one technical issue:

I think our wording is correct.  We want to strip 64 bits (from 128 total).
These 64 bits correspond to 16 hexadecimal digits, called labels in DNS speak,
each separated by a dot.

Does this make sense to you?


Thanks again!
Sebastian
