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.
