Invalid IPv6 address formats possible
Add a host alias, in the IP Address or FQDN box of the 1st entry put:
1:2:3:::4:5:6:8 or 1:2:3:4:5:6:::8 or similar stuff with a triple colon in the middle somewhere.
It validates, but then when the ruleset is written causes "error loading the rules".
so it's a bug in the Net_IPv6 code.
I am happy to have a look tomorrow and sort out what is going wrong with the Net_IPv6 code when faced with more than 2 ":" in a row.

Fixes handling of (what should be invalid) formats:
The above are 6 test cases that are currently allowed as "valid" IPv6 addresses, and will be reported as invalid by the corrected code.
