ip based acls are case-sensitive (relevant only for ipv6)

[xschlef]

the ip based acls are case sensitive:

This will deny the request, as the checks run against the lowercase ip
<Allow address="2001:DB8::5" method="*.*"/>

This will correctly allow the request
<Allow address="2001:db8::5" method="*.*"/>

Does https://gist.github.com/solj/d80d6aadbdf34d621c1cd0845a0b351a fix the issue for you?

This should fix the problem at hand, but I think a proper ipv6 handling should be implemented. Maybe using the ipaddress module?

At least parse the client ip in lowercase as well. IIRC ipv6 is completely case-insensitive.
