Answer reordering

Certain clients are “dumb” and always connect to first IP address or name found in a DNS answer received from resolver instead of picking randomly. As a workaround for such broken clients it is possible to randomize order of records in DNS answers sent by resolver:

options/reorder-rrset: true|false

Default

true

If set, resolver will vary the order of resource records within RR sets. It is enabled by default since 5.3.0.
