private-address defaults in example config

[Luis Ressel]

Hello,

just some minor nitpicking: I've noticed that the example unbound.conf
included in the source tarball includes the directive "private-address:
fd00::/8". This is slightly incomplete; RFC 4193 reserves the whole
fc00::/7 range for local usage.

Therefore, you may want to change this line to "private-address:
fc00::/7" and add "c.f.ip6.arpa." to the local-zone list.

Regards,
Luis Ressel
