 - `logQueries` (optional): Enable this option to log every query received by this DNS Server and the corresponding response answers into the log file.
 - `allowRecursion` (optional): Enable recursion to allow this DNS Server to resolve any domain name.
 - `allowRecursionOnlyForPrivateNetworks` (optional): Enable this option if you want to support recursion only on private networks. Any recursive request from public network will be refused.
+- `randomizeName` (optional): Enables QNAME randomization [draft-vixie-dnsext-dns0x20-00](https://tools.ietf.org/html/draft-vixie-dnsext-dns0x20-00) when using UDP as the transport protocol.
 - `cachePrefetchEligibility` (optional): The minimum initial TTL value of a record needed to be eligible for prefetching.
 - `cachePrefetchTrigger` (optional): A record with TTL value less than trigger value will initiate prefetch operation immediately for itself.
 - `cachePrefetchSampleIntervalInMinutes` (optional): The interval to sample eligible domain names from last hour stats for auto prefetch.
