Configuring Unbound

The Unbound DNS server, from NLnet Labs, is a dedicated caching recursive DNS resolver, that comes with QNAME minimization enabled by default.

The configuration files reside in the /etc/unbound directory. To disable QNAME minimization, add the following to the unbound.conf file, or optionally, to one of the files included by that file, typically in the /etc/unbound/unbound.conf.d directory.

    qname-minimisation: no

You could also add the qname-minimisation line to an existing server: section.
