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:

reorder_RR([true | false])

Parameters

new_value (boolean) – true to enable or false to disable randomization (optional)

Returns

The (new) value of the option

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