Hello Stefan,

First, please also have a look at https://www.unicode.org/reports/tr58/, 
which may be relevant for your work.

Sorry to disagree, but this is NOT about justification. Why do you 
obfuscase domain names and IPv4 literals, but not IPv6 literals? If 
attacks with the former are possible, I'm sure attacks with the later 
also should be possible, and obfuscation has to address this.

Regards,    Martin.
