mresolv - Perform multiple DNS lookups in parallel
mresolv [ -d ] [ -n number ] [ -t timeout ] [ filename... ]
mresolv performs multiple DNS lookups in parallel. Names to query are read from the list of files given on the command line, or from the standard input.
Turn on debugging output.
Set the number of queries to have outstanding at any time.
Set the timeout in seconds. If no replies are received for this amount of time, all outstanding queries will be flushed and new names will be read from the input stream.
