RFE: add IPv6 LLA and ULA to default whitelist

[jeka]

This is an RFE for adding IPv6 Link-Local Address (LLA) range and Unique local address (ULA) to the default whitelist.

So essentially add fd00::/8 and FE80::/10 prefixes. Maybe even IPv6 localhost adrress

Yes, these would be reasonable - want to make a patch?

I can try at least, I just need a few free brain cycles for the task ;)

How would FE800::/10 be represented in the whitelist format of 'whitelist=xxxx:'?
