Re: 6MAN Working group last call: draft-ietf-6man-rdnss-rfc6106bis

Tassos,
Thanks for your comments.

For the first comment, I agree with your suggested sentence for the
clarification:

The link-local addresses MAY be represented in the resolver repository
with their link zone indices in the textual format for scoped addresses as
described in [RFC4007].

For the second comment, I suggest the following sentence for the rationale:

The DNS options from Router Advertisements and DHCP SHOULD be
stored into the DNS Repository and Resolver Repository so that
information from DHCP appears there first and therefore takes
precedence. This is because IPv6 hosts usually prefer DHCP to
RA for their network configuration. Thus, the DNS information
from DHCP takes precedence over that from RA for DNS queries.

Thanks.

Best Regards,
Paul
