* be activated via command line switches. Note that activating both IPv4 and

|
* IPv6 is pointless (and will not work because two UDP and two TCP threads
|

* startup by default. 1 means IPv4, while 0 means IPv6. If support for
|
|
* a protocol was included in the executable, you can specify command line

* error or times out, the query is retried using UDP.
