Unbound 1.6.2rc1 pre-release (EDNS-Subnet)

Hi Andreas,

Are you sure you are not looking at subqueries generated by Unbound,
like root priming queries or queries for the DNSKEY? We do not add ECS
data to these queries.

I do not think we should document the any address case. Sending (privacy
sensitive) ECS data to all nameservers does not sound like a wise thing
to do.

Regards,
-- Ralph
